kernel - Fix kqueue race with NOTE_EXIT
* Fix a kqueue race where the process receiving a NOTE_EXIT can go
away while the NOTE_EXIT is being delivered.
* Add a required PHOLD/PRELE since knote_remove() can block.
* Properly return on-zero if KN_DETACHED is set at the end of knote_release()
so the caller knows to restart the list scan.
