P2P: Do not drop P2P IEs from BSS table on non-P2P scans

P2P: Do not drop P2P IEs from BSS table on non-P2P scans

This could happen when non-P2P station interface runs a scan without P2P
IE in the Probe Request frame. P2P GO would reply to that with a Probe
Response that does not include P2P IE. Do not update the IEs in this BSS
entry to avoid such loss of information that may be needed for P2P
operations to determine group information.
