#     nfs: fix another case of NULL/IS_ERR confusion wrt folio pointers
#     
#     Dan has been improving on the smatch error pointer checks, and pointed
#     at another case where the __filemap_get_folio() conversion to error
#     pointers had been overlooked.  This time because it was hidden behind
#     the filemap_grab_folio() helper function that is a wrapper around it.
