Commit 00b3b9a25e76 ("core: add generic struct ts_session") has
introduced a regression in the ftrace code by introducing a call to
ts_get_current_session() in ftrace_update_times() in replacement of
tee_ta_get_current_session(). At this point it can happen that no
current session exists, in which case the function should simply return.
Unfortunately ts_get_current_session() will call panic() is such a
situation. The proper function is ts_get_current_session_may_fail().
