votequorum: fix segfault in wfa status update
this is a regression introduced by cb5fd775
when reading static config us->flags does not exists yet and therefor
setting it will cause a segfault.
Move the settings after cluster_node *us is created, with the long
term plan to simply kill the whole _static readconfig bits
in favour of dynamic (runtime changeable) bits.
