Rafael Mendonca 304a101616 drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr() ...

[ Upstream commit 90bfee142a ]

If the number of pages from the userptr BO differs from the SG BO then the
allocated memory for the SG table doesn't get freed before returning
-EINVAL, which may lead to a memory leak in some error paths. Fix this by
checking the number of pages before allocating memory for the SG table.
