cpufreq: qcom-cpufreq-hw: Fix uninitialized throttled_freq warning

Browse Source 
Commit 6240aaad75 was supposed to drop the reference count to the OPP,
instead it avoided more stuff if the OPP isn't found. This isn't
entirely correct. We already have a frequency value available, we just
couldn't align it with an OPP in case of IS_ERR(opp).

Lets continue with updating thermal pressure, etc, even if we aren't
able to find an OPP here.

This fixes warning generated by the 'smatch' tool.
