device/resource_allocator_v3: Do not set IORESOURCE_ASSIGNED for size 0 resource 

find_pci_tolm() is updated to ensure that it ignores resources that
have a zero size. This change removes the setting of resource flags to
IORESOURCE_ASSIGNED when the resource is not really allocated any
space by the allocator. It also drops the setting of base to limit
since that is not required anymore.
