drm/amdgpu: debugfs: fix error codes in write functions

2022-04-26T15:52:20Z

There are two error code bugs here. The copy_to/from_user() functions return the number of bytes remaining (a positive number). We should return -EFAULT if the copy fails. Second if we fail because "context.resp_status" is non-zero then return -EINVAL instead of zero.
