resource: Mark res given to resource_assigned() as const

The caller may hold a const struct resource which will trigger an
unnecessary warning when calling resource_assigned() as it will not
modify res in any way.

Mark resource_assigned()'s struct resource *res parameter const to
avoid the compiler warning.
