Luka Gejak 2e3514e63b net: hsr: fix VLAN add unwind on slave errors

When vlan_vid_add() fails for a secondary slave, the error path calls
vlan_vid_del() on the failing port instead of the peer slave that had
already succeeded. This results in asymmetric VLAN state across the HSR
pair.

Fix this by switching to a centralized unwind path that removes the VID
from any slave device that was already programmed.
