mmc: Fix incorrect warning when setting 0 Hz via debugfs
It is possible to turn off the card clock by setting
the frequency to zero via debugfs e.g.
echo 0 > /sys/kernel/debug/mmc0/clock
However that produces an incorrect warning that is
designed to warn if the frequency is below the minimum
operating frequency. So correct the warning.
