Harshit Mogalapalli c5fe3fba1b drm/virtio: Fix error code in virtio_gpu_object_shmem_init() ...

In virtio_gpu_object_shmem_init() we are passing NULL to PTR_ERR, which
is returning 0/success.

Fix this by storing error value in 'ret' variable before assigning
shmem->pages to NULL.

Found using static analysis with Smatch.
