conman:  Fix FrenzyWPACtrl initial status.

go/fibercl/72953 fixed a bug that was depended upon by FrenzyWPACtrl
code that determined whether a connection existed at initialization
time.  This commit fixes that bug by adding the conjunct removed from
attached() to the specific call site which cared about it.
