accel/habanalabs: fix information leak in sec_attest_info()
[ Upstream commit a9f07790a4b2250f0140e9a61c7f842fd9b618c7 ]
This function may copy the pad0 field of struct hl_info_sec_attest to user mode which has not been initialized, resulting in leakage of kernel heap data to user mode. To prevent this, use kzalloc() to allocate and zero out the buffer, which can also eliminate other uninitialized holes, if any.

habanalabs: protect access to dynamic mem 'user_mappings'
When HL_INFO_USER_MAPPINGS IOCTL is called, we copy_to_user from a dynamically allocated memory - 'user_mappings'. Since freeing/allocating it happens in runtime (upon a page fault), it not unlikely to access it even before being initially allocated (i.e., accessing a NULL pointer).
The solution is to simply mark the spot when the err info has been collected, and that way to know whether err info (either page fault or RAZWI) is available to be read.
