memstick: mspro_block: Add error handling support for add_disk()
We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. Contrary to the typical removal which delays the put_disk() until later, since we are failing on a probe we immediately put the disk on failure from add_disk by using blk_cleanup_disk().
