From: Zack Rusin <za...@vmware.com>
Remove the explicit bo_free parameter which was switching between
vmw_bo_bo_free and vmw_gem_destroy which had exactly the same
implementation.
It makes no sense to keep parameter which is always the same, remove it
and all code referencing it. Instead use the vmw_bo_bo_free directly.
