[PATCH i-g-t] lib/amdgpu: Handle -ENODATA in amdgpu_wait_memory

[Jesse.zhang@amd.com]

The amdgpu_wait_memory function currently asserts if the return value
is non-zero and not -ECANCELED. However, -ENODATA is also a valid
error code that can be returned during GPU job timeout recovery,
particularly for queue resets. This patch updates the function to
also accept -ENODATA as a non-fatal error condition.

This change aligns with recent updates in the AMDGPU kernel driver
where -ENODATA is used to indicate queue-specific resets during
timeout recovery, while -ECANCELED or -ETIME is used for full GPU
resets. For more details, see the kernel discussion:
