We no longer know how to contact TLX anyway

GCC 12 trunk started to warn

And while that is arguably a false warning, it points at some dubious code
anyway:  The only reason for the AsynchronLink _bInCall and _pDeleted members is
to potentially SAL_INFO some "valuable historical artefact", if
AsynchronLink::Call were ever called recursively.  But
0de7513cd73f1f35265e42f9a2b9befe81302c2c "osl::Mutex->std::mutex in
AsynchronLink" apparently already argued that such recursive calls can never
happen, as locking _aMutex in a recursive call of Call would now deadlock.
