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

Browse source

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.
