Subject: [PATCH] test/blockdev: remove dependency on brd kernel module

AIO bdev works on any file available from kernel.
blockdev.sh is the only palce that uses the ramdisk
in the current autotest.sh.
After removing the /dev/ram0, aio bdev still gets tested
with regular file.

Note: the QoS functionality done on AIO0 still gets
tested in usual qos.sh tests.
