REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2364
Fixes a new build warning in VS2012 introduced in f8ff4cca7c.
This patch initializes the local variable "Variable" in
VariableServiceGetNextVariableInternal () and the local
variable "RtPtrTrack" in FindVariableInRuntimeCache ().
This enusres the pointers in the structures are initialized
in the case no variable stores exist in the list of variable
stores.
