Jeff Layton fc36d0a42c libceph: abort already submitted but abortable requests when map or pool goes full 
When a Ceph volume hits capacity, a flag is set in the OSD map to
indicate that, and a new map is sprayed around the cluster. With cephfs
we want it to shut down any abortable requests that are in progress with
an -ENOSPC error as they'd just hang otherwise.

Add a new ceph_osdc_abort_on_full helper function to handle this. It
will first check whether there is an out-of-space condition in the
cluster and then walk the tree and abort any request that has
r_abort_on_full set with a -ENOSPC error. Call this new function
directly whenever we get a new OSD map.
