mmc: Remove incorrect cmd->flags usage

There were a couple of drivers that were actually using the flags
field of the cmd structure, despite the fact that no one ever
*set* that field. When we removed the field, those drivers failed
to compile. Replaced the references with the correct usage of
resp_type.
