P2P: Fix D-Bus persistent parameter in group started event on GO

When starting a P2P GO, the struct p2p_go_neg_results may use
persistent_group == 2 to indicate use of persistent reconnect. Setting
ssid->p2p_persistent_group based on this did not take into account this
special case and that ended up in D-Bus code trying to encode 2 as a
DBUS_TYPE_BOOLEAN value which results in an assert from the library. Fix
this by setting ssid->p2p_persistent_group to 0 or 1 instead of raw
params->persistent_group value without any filtering.

This is similar to an earlier fix in commit
112fdee738d28c4e8bfb66ad7202d4348c4e7771 ('P2P: Fix D-Bus persistent
parameter in group started event') that addressed another code path in
sending out this D-Bus signal.
