bdev/null: Support I/O type ABORT

Browse Source 
As malloc bdev module supports I/O type ABORT, it will be helpful
if any bdev module other than NVMe bdev module supports I/O type
ABORT.

Update bdev_null_io_type_supported() to return true for
SPDK_BDEV_IO_TYPE_ABORT and update bdev_null_submit_request() to
try aborting the target I/O if queued.
