mmc: core: Fix MMC clock scaling in case of tuning failure

When the clock scaling state is changed from MMC_LOAD_LOW to
MMC_LOAD_HIGH, the clocks are first scaled up and then tuning
is performed. But in case of tuning failure, the current code
does nothing but still retain the previous clock scale stats
(state and curr_freq within struct clk_scaling). Hence, correct
it to scale down the clocks in case of tuning failure so that
clock scaling stats reflect the correct status. This also helps
proceed with data transfers at lower clock rate in such cases.
