nl80211: don't hold RTNL in color change request

BugLink: https://bugs.launchpad.net/bugs/1981864
[ Upstream commit 1b550a0bebfc0b69d6ec08fe6eb58953a8aec48a ]

It's not necessary to hold the RTNL across color change
requests, since all the inner locking needs only the
wiphy mutex which we already hold as well.
