push: acquire local 'wlock' if "pushback" is expected (BC) (issue4596)

If the client allows "pushback", the bundle2 served back by the server may
contains parts that will write to the repository. Such parts may require the
'wlock' (eg: bookmark) so we acquire it in advance to make sure it got acquired
before the 'lock'.
