[PATCH] drm/vmwgfx: Fix NULL vs error pointer bug in vmw_prime_import_sg_table()

[Dan Carpenter]

The vmw_prime_import_sg_table() function is expected to return error
pointers on error and not NULL.  Otherwise it leads to a NULL dereference
in the caller drm_gem_prime_import_dev().

Change the NULL to ERR_PTR(-ENOMEM).
