Description of problem:
IPv6 RA timeout is derived from /proc/sys/net/ipv6/conf/$dev/router_solicitations * /proc/sys/net/ipv6/conf/$dev/router_solicitation_interval. But is clamped between 30 and 120 secs.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create dummy interface
1. Set router_solicitations and router_solicitation_interval to 15 for the dummy
2. Enable RA via NetworkManager for the dummy
RA timeout is set for 120 secs
RA timeout 225

This bug badly impacts RHV as it breaks connectivity for VMs.

The fix is simple and self-contained, it doesn't impact other parts of code except IPv6 RA. We have 900+ tests in CI that covers many features, including IPv6 RA, so the regression risk is very low.

The bug is already fixed upstream.
