vdisk_blockio: Specify REQ_SYNC for synchronous I/O requests
Using READ_SYNC instead of READ increases the priority of read requests.
Using WRITE_SYNC instead of REQ_WRITE increases the priority of write
requests and avoids that the CFQ scheduler queues such writes waiting
for further write requests.

vdisk_blockio: Reenable COMPARE AND WRITE
The COMPARE AND WRITE implementation has been tested as follows against
an SCST vdisk_blockio device:
lba=7
bdev=$bdev
for ((i=0;i<4;i++)); do dd if=/dev/urandom of=b$i bs=8k count=1; done
for p in "0 1" "1 2" "2 3" "3 0"; do set $p; cat b$1 b$2 >b$1$2; done
dd if=/dev/urandom of=$bdev
dd if=b0 of=$bdev seek=$lba
md5sum $bdev
for ((i=0;i<10000;i++)); do for f in b01 b12 b23 b30; do sg_compare_and_write -l $lba -i $f -n 16 -x 16384 $bdev; done; done
md5sum $bdev
