Fix taskq_wait_id()
The existing taskq_wait_id() function can incorrectly block
indefinitely. Reimplement it more simply using wait_event()
in a similar fashion to taskq_wait_all().
This flaw was uncovered in the context of moving vn_rdwr() to
a taskq. Previously taskq_wait_id() had no consumers outside
the SPLAT task framework which is why the issue went unnoticed.
