Commit44645f87de("mmc: Fix mmc_switch excessive timeout") introduced a side effect where CMD13 SEND_STATUS is issued in case mmc_wait_dat0() does not return -ENOSYS and $send_status is not set. This happens on all hardware which does implement .mmc_wait_dat0 callback, e.g. i.MX8M . This leads to lengthy timeout before booting OS in case of eMMC in one of the HS200/HS400 modes, since the card cannot respond to CMD13 while downgrading from HS200/HS400 to regular HS mode. Fix this by adding the missing conditional.
