DPP: Send connection status result if disconnected during 4-way HS

DPP: Send connection status result if disconnected during 4-way HS

Connection status result was reported during failed 4-way handshake if
that failure might have been due to an incorrect phassphrase/password.
4-eay handshake might fail for other reasons and if that is the case,
the connection status result is delayed unnecessarily long untile the 15
second timeout occurs.

Optimize this by sending out the connection status result in all
disconnection cases that happen before the 4-way handshake has been
completed successfully.
