When a ucom(4) is removed, it frees the tty with ttyfree(). However if
anyone is waiting with kqueue their knotes may still have a reference to
the tty and later try to use it in the filt_tty* functions.
To avoid this, walk the knotes in ttyfree(), remove them from the tty's
list and invalidate them by setting kn_hook to NODEV. The filter
functions can then check for this and safely ignore the knotes.
