netavark: create bridge: Netlink error: File exists (os error 17)

In a recent OSCI Bot run for a CentOS Stream 9 MR for glibc: redhat/centos-stream/rpms/glibc!286 (merged)

We saw the following Testing Farm failure: https://artifacts.osci.redhat.com/testing-farm/7af07e76-4cf4-4b8b-9920-448a38461d20/

        # stderr (2 lines)
        # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        time="2025-04-09T18:43:04Z" level=warning msg="The input device is not a TTY. The --tty and --interactive flags might not work properly"
        Error: netavark: create bridge: Netlink error: File exists (os error 17)
        # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I don't know if this is an osci.rpmdeplint failure or tmt failure.

The netlink error seemed suspicious enough that I thought I'd file an issue here.
