mmc: core: Remove flag MMC_PM_WAKE_SDIO_IRQ in mmc_resume_host

MMC_PM_WAKE_SDIO_IRQ flag is used by platform driver(sdhci-msm
here) to determine if SDIO wakeup IRQ needs to be enabled
or not. If this flag is not removed in every mmc_resume_host,
then while suspend, platform driver will configure the sdio
wakeup IRQ even though wlan is disabled from UI.
This flag can be enabled by wlan driver before entring into suspend.
In this case since Wlan is not enable and thus not entering WoW mode,
pull up present on this SDIO GPIO line will pull the line high (which
otherwise is pulled low by wlan firmware in WoW mode and triggers
interrupt by pulling it high in WoW mode) which eventually will
trigger a false SDIO wakeup interrupt thus breaking the suspend
everytime.
Hence disable the flag everytime in mmc_sdio_resume and let
wlan driver enables it (-by sdio_set_host_pm_flags)
before entering into suspend if needed
for sdio wakeup part.
