[PATCH] drm/amdgpu_gem: fix error handling path in amdgpu_gem_va_update_vm

[Gustavo A. R. Silva]

Currently, if amdgpu_vm_bo_update() fails, the returned error
is being ignored.

Fix this by properly checking _r_ after calling amdgpu_vm_bo_update.
Also, remove redundant code just before label _error_.
