mmc: mmci: stm32: correctly check all elements of sg list

BugLink: https://bugs.launchpad.net/bugs/1969107
commit 0d319dd5a27183b75d984e3dc495248e59f99334 upstream.

Use sg and not data->sg when checking sg list elements. Else only the
first element alignment is checked.
The last element should be checked the same way, for_each_sg already set
sg to sg_next(sg).
