rtnetlink: use xarray iterator to implement rtnl_dump_ifinfo()

Browse source

Adopt net->dev_by_index as I did in commit 0e0939c0ad
("net-procfs: use xarray iterator to implement /proc/net/dev")

This makes sure an existing device is always visible in the dump,
regardless of concurrent insertions/deletions.

v2: added suggestions from Jakub Kicinski and Ido Schimmel,
    thanks for the help !
