redhat: Fix command sequence for restarting net interface
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2098233
Apparently the down and up commands need to be run in the same command, so connect them together with "&&" operator. Also re-implement restart_if ot handle warnings same wat as other distros
