Subject: netfilter: nf_queue: make nf_queue_entry_release_refs static
Patch-mainline: v5.7-rc1
Git-commit: dd3cc111f2e3220ddc9c4ab17f13dc97759b5163
References: bsc#1176447

This is a preparation patch, no logical changes.
Move free_entry into core and rename it to something more sensible.

Will ease followup patches which will complicate the refcount handling.
