Fix build warnings when CONFIG_ACPI is not enabled:

include/linux/dmar.h:248:46: warning: 'struct acpi_dmar_header' declared inside parameter list
include/linux/dmar.h:248:46: warning: its scope is only this definition or declaration, which is probably not what you want
include/linux/dmar.h:252:46: warning: 'struct acpi_dmar_header' declared inside parameter list
