resources: when allocate_resource() fails, leave resource untouched
When "allocate_resource(root, new, size, ...)" fails, we currently
clobber "new". This is inconvenient for the caller, who might care
about the original contents of the resource.
For example, when pci_bus_alloc_resource() fails, the "can't allocate
mem resource %pR" message from pci_assign_resources() currently contains
junk for the resource start/end.
This patch delays the "new" update until we're about to return success.
