kernel - Fix system lockup w/ kqueue based select/poll due to dup2()
* dup2() was not calling knote_fdclose() on the original descriptor being
replaced
* fdfree() (called by exit) was not cleaning out knotes either, though
exit*() probably took care of it already when it closed the descriptors.
* Assert that a file has no knotes on the last fdrop().
