mmc: sdhci-msm: No need to free-up dll-hsr table

Dll-hsr table getting freed-up in non-error case as well so dll
registers are getting updated with unexpected values.

In fact there is no need to free-up this table even in error cases.
If dll-hsr property is not supplied at all from device-tree then
the memory for the dll-hsr table won't get allocated. And if it's
supplied but wrongly (with the wrong number of entries), memory
for the table gets allocated but the driver won't proceed with the
probe. So no need to free up dll-hsr table upon errors.
