P2P: Clear p2p_go_group_formation_completed on GO start

Previously, this variable did not necessarily get cleared between group
formations and could result in some of the workaround operations from
not being executed after the first group formation when using the same
interface for all P2P groups. Fix this by clearing the variable whenever
starting the GO to make sure it is used consistently for each group
formation.
