All callers of __mmc_switch() should now be specifying a valid timeout for the CMD6 command. However, just to be sure, let's print a warning and default to use the generic_cmd6_time in case the provided timeout_ms argument is zero. In this context, let's also simplify some of the corresponding code and clarify some related comments.
