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))

return BLK_STS_IOERR;
Hence this patch that verifies that the zone size is a power of two.
Note that this is already checked in blk_revalidate_disk_zones(), but it
does not hurt to add the check.
If the block layer would be modified such that support is added for zones with
a size that is not a power of two I think we will really need this check.
Thanks,
