sd: Avoid access to NULL BlockDriverState
Commit 4f8a066b5fc254eeaabbbde56ba4f5b29cc68fdf (blockdev: Remove IF_*
check for read-only blockdev_init) added a usage of bdrv_is_read_only()
to sd_init(), which is called for versatilepb, versatileab and
xilinx-zynq-a9 machines among others with NULL argument by default,
causing the new qom-test to fail.
Add a check to prevent this.
