os/bluestore/BlueFS: prevent _compact_log_async reentry

_should_compact_log uses new_log != nullptr to tell whether compaction is
already in progress, but we don't set it until we are midway through the
process.  Set it at the top of the method to prevent reentry.

See 455cc6cea2e5e8bc1126b5047b6003fa583af1b5, which failed to implement
this properly.
