mmc: dw_mmc: fix dw_mci_get_cd
bf626e5550f24aec ("mmc: dw_mmc: use slot-gpio to handle cd pin") caused
CDETECT to be ignored, since negated return value of mmc_gpio_get_cd(mmc)
can not be checked by IS_ERR_VALUE.
Also, add spin_lock_bh(&host->lock) for atomic access to
DW_MMC_CARD_PRESENT, otherwise sd detect may occasionally fail.
