Subject: [PATCH 1/1] Revert "policy: track the autoconnect retries in devices
 for multi-connect"

With multi-connect enabled, this can cause infinite retries to autoconnect,
see [1].

That has bad consequences for example in initrd, where
nm-wait-online-initrd.service would wait up to one hour before failing
and blocking boot.

This reverts commit 1656d82045343b5af5b86cf129d4f2b12540b277.

[1] https://bugzilla.redhat.com/show_bug.cgi?id=2039734#c5

Fixes: 1656d8204534 ('policy: track the autoconnect retries in devices for multi-connect')
(cherry picked from commit aec7ae8279cc9b3de7e75140b75fe997f43700fc)
(cherry picked from commit ba663123669ae1a5670e4a85ce2cf520fea875f6)
