scsi: sd: sd_zbc: Verify that the zone size is a power of two

The following check in sd_zbc_cmnd_checks() can only work correctly if the
zone size is a power of two:

	if (sector & (sd_zbc_zone_sectors(sdkp) - 1))
		/* Unaligned request */
		return BLK_STS_IOERR;

Hence this patch that verifies that the zone size is a power of two.
