[PATCH v1 1/1] OvmfPkg/PlatformDxe: Check RouteConfig arguments for spec compliance

["Yuan Yu" <yuanyu@google.com>]

Per UEFI Spec 2.9, EFI_HII_CONFIG_ROUTING_PROTOCOL.RouteConfig()
should return EFI_INVALID_PARAMETERS if caller passes in a NULL for
the Configuration parameter (see 35.4 EFI HII Configuration Routing
Protocol).

Add a check to return EFI_INVALID_PARAMETERS when Configuration is NULL.
