ArmVirtPkg/FdtPciPcdProducerLib: zero init local var to please GCC 4.8

GCC 4.8 in RELEASE mode complains about GetPciIoTranslation () potentially
not assigning IoTranslation, but does not notice that it returns failure in
this case, which means IoTranslation is never referenced *unless* it has
been assigned. So simply set IoTranslation to zero to help the compiler.
