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.
