Add @chsize param to the function which, if non-zero, would represent
the chunk size to be used for comparison.  If it's zero, then
BDRV_SECTOR_SIZE is used as default chunk size, which is the previous

In particular, we're going to use this param in img_rebase() to make the
write requests aligned to a predefined alignment value.
