drm/amdgpu: prevent BO_HANDLES error from being overwritten

Browse Source 
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.

Fixes: fec5f8e8c6 ("drm/amdgpu: disallow multiple BO_HANDLES chunks in one submit")
