All error handling paths go to "out", except this one. Before the commit in
Fixes, error in the previous code would also end to "out".

So, go to "out" also in this case to free some resources before returning.

Fixes: 62262dd00c31 ("wifi: cfg80211: disallow SMPS in AP mode")

Compile tested only

Changes in v2:
  - Fix the subject

v1: apparently never reached lore, certainly because of the duplicated
subject with [1]
