Log Message:
Fix that rump.ifconfig shmifN destroy hangs up

rump.ifconfig shmifN destroy sometimes hangs up on closing a file
descriptor of kqueue under heavy load. It seems it happens because of
a race condition between closing a fd and kevent to the same fd on
another kthread for packet Rx. Fix it by executing the close operation
after the kthread left.
