drm/amdgpu: Forward soft recovery errors to userspace

Browse Source 
commit 829798c789f567ef6ba4b084c15b7b5f3bd98d51 upstream.

As we discussed before[1], soft recovery should be
forwarded to userspace, or we can get into a really
bad state where apps will keep submitting hanging
command buffers cascading us to a hard reset.
