libceph: make abort_on_full a per-osdc setting
The intent behind making it a per-request setting was that it would be set for writes, but not for reads. As it is, the flag is set for all fs/ceph requests except for pool perm check stat request (technically a read). ceph_osdc_abort_on_full() skips reads since the previous commit and I don't see a use case for marking individual requests.
