md/raid5: use async_tx_quiesce() instead of open-coding it.
handle_stripe_expansion contains:
if (tx) {
async_tx_ack(tx);
dma_wait_for_async_tx(tx);
}
which is very similar to the body of async_tx_quiesce(),
except that the later handles an error from dma_wait_for_async_tx()
(admittedly by panicing, but that decision belongs in the dma
code, not the md code).
So just us async_tx_quiesce().
