[PATCH 4/4] Fix CodeQL issue

[Owen Smith <owen.smith@xxxxxxxxx>]

ProcNumber should be initialized before calling KeGetCurrentProcessorNumberEx
incease the call fails and doesnt populate the PROCESSOR_NUMBER. This function
should never fail but the annotations in Windows headers dont state this
correctly.
