msm: camera: sensor: Remove NULL set for regulator phandle

Regulator_get is being moved with probe time for opertional
performance improvement. With this change regualtor phandle can
only be derive at power cycle. In case of power_on/down failure case
currently regulator phandle is set with NULL which can cause
failure in power related operation in all future sessions. This change
removes NULL setting to regulator phandle in failure case.
