ASoC: SOF: Intel: hda: do not leave clock gating off upon error 

The misc clock gating (MISCBDCGE) is disabled for controller reset and
reenabled once reset is complete.

Fix the case when error happens during reset, and clock gating is
left disabled. The clock gating should be reenabled also in this case.
