Subject: [PATCH][next] aio: fix missing break in switch statement

From: Colin Ian King <colin.king@...onical.com>

The addition of the IOCB_CMD_POLL command removed the break
statement for the IOCM_CMD_FDSYNC. From my understanding, this
should not have been removed as the fall-through does not seem
to make sense.  Fix this by adding the break back again.
