[PATCH 1/2] libceph: For nofail == false, if __map_request failed,it should unregister.

[majianpeng <majianpeng@xxxxxxxxx>]

For nofail == false  request, if __map_request failed, the caller do
cleanup work,like release the relative pages.It doesn't make any sense
to retry this request.So only give up it.
