vfio/type1: Catch zero from pin_user_pages_remote()
pin_user_pages_remote() can currently return zero for invalid args
or zero nr_pages, neither of which should ever happen. However
vaddr_get_pfns() indicates it should only ever return a positive
value or -errno and there's a theoretical case where this can slip
through and be unhandled by callers. Therefore convert zero to
-EFAULT.
