resource: Add __resource_contains_unbound() for internal contains checks

Browse source

__find_resource_space() currently uses resource_contains() but for
tentative resources that are not yet crafted into the resource tree. As
resource_contains() checks that IORESOURCE_UNSET is not set for either of
the resources, the caller has to hack around this problem by clearing the
IORESOURCE_UNSET flag (essentially lying to resource_contains()).

Instead of the hack, introduce __resource_contains_unbound() for cases like
this.
