- Remove redundant assertions that the driver lock is not held in attach()

  and detach() since mtx_lock() will assert that already since the driver
  lock is not recursive.
- Move the call to callout_init_mtx() before hme_stop() so that the
  callout_stop() in hme_stop() doesn't operate on an uninitialized callout
  structure during attach.
