Rob Norris 468d22d60c txg_wait_synced_flags: add TXG_WAIT_SUSPEND flag to not wait if pool suspended
This allows a caller to request a wait for txg sync, with an appropriate
error return if the pool is suspended or becomes suspended during the
wait.

To support this, txg_wait_kick() is added to signal the sync condvar,
which wakes up the waiters, causing them to loop and reconsider their
wait conditions again. zio_suspend() now calls this to trigger the break
if the pool suspends while waiting.
