However, EmuVariableFvbRuntimeDxe is excluded from the SMM_REQUIRE build, and then noone consumes PcdEmuVariableNvStoreReserved. Don't waste reserved memory whenever that's the case. (Even a dynamic default for PcdEmuVariableNvStoreReserved would be unnecessary; but that way the PcdSet64S() call in the ReserveEmuVariableNvStore() function doesn't compile.)
