P2P: Consider BSS entry pending for P2P joining as a known BSS

Consider the BSS entry that is pending for the P2P group join operation
also as a known network along with the existing configured networks.
This prevents removal of the BSS entry that is still in the process of
P2P join operation from the BSS table when the number of entries exceed
bss_max_count.
