[PATCH linux-next] wifi: nl80211: fix double wdev_put() from the wireless-next merge

[Sasha Levin <sashal@kernel.org>]

The wireless tree has commit 5e25f6b1b18d ("wifi: nl80211: fix ERR_PTR
use on wdev disappearance"), which returns right away when
__nl80211_lock_held_wdev() fails. wireless-next changed the same lines
in commit a357675fd740 ("wifi: cfg80211: enable context analysis") and
still jumps to out_err there. The merge kept the wireless-next version.

That is a double put: the helper has already dropped the wdev reference
by the time it fails, and out_err drops it again.

Just return the error, like the wireless fix does.

Mark, this is against next-20261110. Please fold it into the wireless-next
merge.

Johannes, wireless-next has the same double put on its own until wireless
gets merged into it.

Found by comparing with our llminus-assisted integration tree. Build tested
only.
