Log Message:
allow cv_signal() immediately followed by cv_destroy().
this sequence is used by ZFS in a couple places and by supporting it
natively we can undo our local ZFS changes that avoided it.
note that this is only legal when all of the waiters use cv_wait()
and not any of the other variations, and lockdebug will catch
any violations of this rule.
