PCI: Add debug print when releasing resources before retry

Browse source

PCI resource fitting is somewhat hard to track because it performs many
actions without logging them. In the case inside
__assign_resources_sorted(), the resources are released before resource
assignment is going to be retried in a different order. That is just one
level of retries the resource fitting performs overall so tracking it
through repeated assignments or failures of a resource gets messy rather
quickly.

Simply announce the release explicitly using pci_dbg() so it is clear what
is going on with each resource.
