[PATCH] P2P: Cleanup p2p_invite argument passing for ctrl interface

[nirav shah]

The p2p_invite api requires group interface name or persistent
group id with peer address to which the invitation is to be sent.
However ctrl interface documentation and argument check function
does not mandate this. Enforcing this in the ctrl interface.
