[PATCH] Append P2P device address to AP-STA-CONNECTED event for P2P

[Jithu Jance]

For P2P, the p2p_connect takes in device address argument to make a
connection. However the connected event [AP-STA-CONNECTED] comes
with interface address. The application listening on events would find it
difficult to map interface address to the p2p device address which is
provided for connection.

This patch appends P2P device address to AP-STA-CONNECTED event for P2P
Client connection.
This will help applications to easily map the P2P interface address to P2P
device address on CONNECTED event. For NON-P2P case, it will just print the
usual STA mac
address alone.

Kindly see whether the patch is okay.
