[pve-devel] [PATCH pve-manager 1/2] network-interface-pinning: fix subsequent invocations

[Stefan Hanreich]

The fix introduced in 5b5db0e67 fixed the scenario where pins were
already applied, but broke the case where they weren't yet applied,
since now not-yet-applied pins would get overwritten again on
subsequent invocations of the pinning tool.

Move the check for the same name to the update_etc_network_interfaces
call, where it is actually required - instead of filtering already in
the resolve_pinned function, which is also used in the generate body
to filter eligible links for pinning.
