mtd: rawnand: qcom: Fix broken OP_RESET_DEVICE command in qcom_misc_cmd_type_exec()

commit b61bb5bc2c1cd00bb53db42f705735db6e8700f0 upstream.

While migrating to exec_ops in commit a82990c8a409 ("mtd: rawnand: qcom:
Add read/read_start ops in exec_op path"), OP_RESET_DEVICE command handling
got broken unintentionally. Right now for the OP_RESET_DEVICE command,
qcom_misc_cmd_type_exec() will simply return 0 without handling it. Even,
if that gets fixed, an unnecessary FLASH_STATUS read descriptor command is
being added in the middle and that seems to be causing the command to fail
on IPQ806x devices.

So let's fix the above two issues to make OP_RESET_DEVICE command working
again.

Pull MTD fixes from Miquel Raynal:
"In the raw NAND subsystem, the major fix prevents using cached reads
with devices not supporting it. There was two bug reports about this.

Apart from that, three drivers (pl353, arasan and marvell) could
sometimes hide page program failures due to their their own program
page helper not being fully compliant with the specification (many
drivers use the default helpers shared by the core). Adding a missing
check prevents these situation.

Finally, the Qualcomm driver had a broken error path.

In the SPI-NAND subsystem one Micron device used a wrong bitmak
reporting possibly corrupted ECC status.

Finally, the physmap-core got stripped from its map_rom fallback by
mistake, this feature is added back"

mtd: rawnand: qcom: Unmap sg_list and free desc within submic_descs()

There are two types of dma descriptors being used in this driver allocated
by, prepare_bam_async_desc() and prep_adm_dma_desc() helper functions.
These functions map and prepare the descriptors to be used for dma
transfers.

And all the descriptors are submitted inside the submit_descs() function.
Once the transfer completion happens, those descriptors should be unmapped
and freed as a part of cleanup.

Currently, free_descs() function is doing the said cleanup of descriptors.
But the callers of submit_descs() are required to call free_descs() in both
the success and error cases.

Since there are no other transactions need to be done after submit_descs(),
let's just move the contents of free_descs() inside submit_descs() itself.

This makes sure that the cleanup is handled within the submit_descs()
thereby offloading the cleanup part from callers.

While at it, let's also rename the return variable from "r" to "ret".

Instead of allocating a structure on the stack with random data and then
expect the callee to perform the initialization (which is, in general,

needed. It is probably safer to do so, so we limit the timeframe when
dirty data could actually be accessed by mistake.
