HAMMER VFS - Fix umount panic related to volume flush

* A volume undergoing I/O as-of the time of a umount can recurse within
  hammer_io_release() due to improper ref-count handling.

* Properly reference and flus hthe volume during umount instead of
  trying to call hammer_io_release() directly.
