mmc: core: Attribute the IO wait time properly in mmc_wait_for_req_done()

In mmc_wait_for_req_done() function, change the call wait_for_completion()
to wait_for_compltion_io(). This change makes the kernel account for
wait time as I/O wait and through another configuration, this io wait
is treated as busy which makes the acpu clock to scale up.
