kernel - Bring devfs_assume_knotes() uptodate and fix panic

* devfs_assume_knotes() was blindly transfering the knotes without
  properly acquiring their soft-lock.

  The problem was easily reproducable by running 'moused -p /dev/ums0'
  and then unplugging the mouse.

* Move the core of the routine into a new procedure in kern_event.c
  called knote_assume_knotes() which properly acquires and releases
  the underlying knotes.
