msm: thermal: Remove proactive vdd restriction during probe

Vdd restriction probe will apply mitigation, which will be cleared
later during the KTM boot mitigation. KTM now initializes the
data structures to do this mitigation only after vdd restriction probe.

So remove this pro-active mitigation in the probe function. KTM boot
mitigation will be started immediately after the KTM probe and can take
care of this mitigation.
