Kevin Wolf 2f3b6e61f6 block/io: Ignore FUA with cache.no-flush=on 
For block drivers that don't advertise FUA support, we already call
bdrv_co_flush(), which considers BDRV_O_NO_FLUSH. However, drivers that
do support FUA still see the FUA flag with BDRV_O_NO_FLUSH and get the
associated performance penalty that cache.no-flush=on was supposed to
avoid.

Clear FUA for write requests if BDRV_O_NO_FLUSH is set.
