drm/vc4: copy_to_user() returns the number of bytes remaining
The copy_to/from_user() functions return the number of bytes remaining
to be copied. We want to return error codes here.
Also it's a bad idea to print an error message if a copy from user fails
because users can use that to spam /var/log/messages which is annoying
so I removed those.
Fixes: 214613656b51 ('drm/vc4: Add an interface for capturing the GPU state after a hang.')
