FreeBSD: Improve taskq wrapper
- Group tqent_task and tqent_timeout_task into a union.  They are
never used same time. This shrinks taskq_ent_t from 192 to 160 bytes.
 - Remove tqent_registered.  Use tqent_id != 0 instead.
 - Remove tqent_cancelled.  Use taskqueue pending counter instead.
 - Change tqent_type into uint_t.  We don't need to pack it any more.
 - Change tqent_rc into uint_t, matching refcount(9).
 - Take shared locks in taskq_lookup().
 - Call proper taskqueue_drain_timeout() for TIMEOUT_TASK in
taskq_cancel_id() and taskq_wait_id().
 - Switch from CK_LIST to regular LIST.
