Mohammed AneesandGreg Kroah-Hartman dc79c24e58 drm/amdgpu: prevent BO_HANDLES error from being overwritten ...

commit c0ec082f10 upstream.

Before this patch, if multiple BO_HANDLES chunks were submitted,
the error -EINVAL would be correctly set but could be overwritten
by the return value from amdgpu_cs_p1_bo_handles(). This patch
ensures that if there are multiple BO_HANDLES, we stop.
