p2p: set p2p probe response vendor information elements for p2p dev interface

The p2p dev interface is not a top interface, but a child of
the global interface. As a result, the response vendor ies are
always skipped.

Bug: 197695047
Test: use WifiP2pManager::setVendorElements to set VSIEs on Pixel 6 Pro
