If suspend called when kmmcd is doing host->ops->disable,
as kmmcd already increased host->en_dis_recurs to 1, the mmc_host_enable
in suspend function will return directly without increase the nesting_cnt,
which will cause the followed register access carried out to the disabled host.
mmc_suspend_host will enable host itself. No need to enable host before it.
Also works on kmmcd will get flushed in mmc_suspend_host, enable host after
it will be safe. So make the mmc_host_enable after it.
