Peter Zijlstra aee9d30b97 x86,static_call: Fix static-call vs return-thunk
Commit

  7825451fa4 ("static_call: Add call depth tracking support")

failed to realize the problem fixed there is not specific to call depth
tracking but applies to all return-thunk uses.

Move the fix to the appropriate place and condition.
