ANDROID: mmc: sdio: Disable retuning in sdio_reset_comm()

Since sdio_reset_comm() re-initializes the SDIO card, disable retuning
before idling and shutting down the card.  Tuning will be re-enabled (if
necessary) in mmc_sdio_init_card().

BUG=chrome-os-partner:46444
TEST=With CL:311815, toggle WiFi on/off on Smaug and observe that the
WiFi card comes back up and is able to tune successfully.
