ceph: make mds requests killable, not interruptible
The underlying problem is that many mds requests can't be restarted. For
example, a restarted create() would return -EEXIST if the original request
succeeds. However, we do not want a hung MDS to hang the client too. So,
use the _killable wait_for_completion variants to abort on SIGKILL but
nothing else.
