If max_seg_size is unaligned, mmc_test_map_sg() may create sg element
sizes that are not aligned with 512 byte. Fix, align max_seg_size at

Shouldn't we align this to host->max_blk_size supported by controller? I
guess there are some extended capacity cards which claim to support
4096bytes as block size. I am not sure if any card/controller supports
this mode yet.
