Subject: libceph: unregister request in __map_request failed and nofail == false
From: majianpeng <majianpeng@xxxxxxxxx>
commit 73d9f7eef3d98c3920e144797cc1894c6b005a1e upstream.
For nofail == false request, if __map_request failed, the caller does
cleanup work, like releasing the relative pages. It doesn't make any sense
to retry this request.
