Avoid INVARIANTS panic destroying an in-use tap(4)
The requirement (implied by the KASSERT in tap_destroy) that the tap is
closed isn't valid; destroy_dev will block in devdrn while other threads
are in d_* functions.
Note: if_tun had the same issue, addressed in SVN revisions r186391,
r186483 and r186497. The use of the condvar there appears to be
redundant with the functionality provided by destroy_dev.
