MdeModulePkg/ReportStatusCodeRouter: Clear RSC Data buffer if Data is NULL 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1969

ReportDispatcher() may be invoked with a NULL Data argument. When TPL is
less than TPL_HIGH_LEVEL and Data is NULL, the EFI_STATUS_CODE_DATA
structure inside RscData should be cleared so listeners will not receive
data from a previous operation.
