When __mmc_blk_ioctl_cmd() calls card_busy_detect() to verify that the card's states moves back into transfer state, the polling with CMD13 is done without any delays in between the commands being sent. Rather than fixing card_busy_detect() in this regards, let's instead convert into using the common mmc_poll_for_busy(), which also helps us to avoid open-coding.
