Use P2P_IE_VENDOR_TYPE more consistently

Browse Source 
Previously, both this and combination of OUI_WFA and P2P_OUI_TYPE were
used. Using the full 32-bit value as a single operation saves a bit in
code size, so start moving towards using it more consistently when
writing or finding the P2P vendor specific element.
