wifi: mac80211: fix prep_connection error path

[ Upstream commit 2e6bd24339a6ff04413b2e49c0f2672d6f0edfa5 ]

If prep_channel fails in prep_connection, the code releases
the deflink's chanctx, which is wrong since we may be using
a different link. It's already wrong to even do that always
though, since we might still have the station. Remove it
only if prep_channel succeeded and later updates fail.
