devfs: make destroy_dev() a release barrier for cdevpriv destructors runs
Ensure that all destructors for cdevpriv finished running before
destroy_dev() returns to the caller. Otherwise, since
devfs_destroy_cdevpriv() removes the cdevpriv data from the list, drops
the cdevpriv_mtx, and then starts the destructor, it is possible for
destroy_dev() to return before destructor finished in other thread.
This should allow drivers to safely remove cdev instance data that might
be referenced by cdevpriv data.

(cherry picked from commit 4dbe6628179d8e6bf400bfdb4bfa869bdc102a56)
I did not merged this to 15 (or 14) because if_tun has a regressions
requiring some fixes from kevans, which were not merged.
Ah, woof- sorry, it's been busy here. I'll go ahead and merge the fix to
stable/15. The relevant
feature won't be merged to stable/14, so it should be safe to take it back
there as well.
Thanks,
