wifi: mac80211: don't unreserve never reserved chanctx
[ Upstream commit a6d521bafcb290294128a51b13dbf4baae5748fc ]
If a link has no chanctx, indicating it is an inactive link
that we tracked CSA for, then attempting to unreserve the
reserved chanctx will throw a warning and fail, since there
never was a reserved chanctx. Skip the unreserve.
