The commit 25f9080576b9 ("f2fs: add async reset zone command support")
introduced "async reset zone commands" by calling
__submit_zone_reset_cmd() in async discard operations. However,
__submit_zone_reset_cmd() is called regardless of zone type of discard
target zone. When devices have conventional zones, zone reset commands
are sent to the conventional zones and cause I/O errors.
Avoid the I/O errors by checking that the discard target zone type is
sequential write required. If not, handle the discard operation in same
manner as non-zoned, regular block devices. For that purpose, add a new
helper function f2fs_bdev_index() which gets index of the zone reset
target device.
Fixes: 25f9080576b9 ("f2fs: add async reset zone command support")
