Eliminate busy loop during pvcreate of a "normal" partition. _md_sysfs_attribute_snprintf() would busy loop if the device it was given was not a blkext-based MD partition. Rather than being cute with a busy-loop prone 'goto check_md_major' in _md_sysfs_attribute_snprintf(): explicitly check if the provided device is a blkext-based partition (blkext_major()); and then check that the get_primary_dev() determined parent is an MD device (md_major()).
