Subject: [PATCH net-next] Revert "net: devlink: add RNLT lock assertion to devlink_compat_switch_id_get()"

This reverts commit 6005a8aecee8afeba826295321a612ab485c230e.

The assertion was intentionally removed in commit 043b8413e8c0 ("net:
devlink: remove redundant rtnl lock assert") and, contrary what is
described in the commit message, the comment reflects that: "Caller must
hold RTNL mutex or reference to dev...".
