P2P: Set user_initiated_pd separately from the join parameter

Browse Source 
p2p_prov_disc_req() used the join parameter to figure out whether the PD
request was a user initiated or not. This does not cover all use cases
of PD, so add a separate parameter to allow caller to indicate whether
the user requested the operation.
