The core sends this command anyhow shortly after calling .init(). So doing it in bcm2835_mci_reset() is only overhead if it succeeds and if there is a problem it is noticed a tad earlier which has little benefit compared to the timeout in bcm2835_mci_wait_command_done(). So simplify and drop the transfer.
