kernel - Fix hammer recovery crash (due to recent syncer work)

* Unconditionally create a syncer thread for each mount.  This way we can
  create the thread prior to calling VFS_MOUNT.

* hammer(1) needs to acquire vnodes and potentially issue vn_rdwr()'s during
  mount for recovery purposes.  This syncer thread is expected to already
  exist.  (and it does now).

* Remove the default syncer thread.

* rewrite speedup_syncer().
