osd/PG: allow preemption of remote backfill reservations

If we have granted a remote backfill reservation, and a higher priority
request comes in, send a REVOKE message back to the primary and drop the
reservation (allowing the higher-priority reservation to be GRANTed).

We can only do this if the primary is running new code because it must
understand the REVOKE message.
