Disconnect after connect using WPS

[Avinash Patil]

Hello Paskal,

Once WPS exchange is complete, you are supposed to initiated connection
from external station device manually. WPS exchange is used to generate
config file required for this connection. Deauthentication from mwifiex AP
is expected after successful WPS exchange.

Please let me know if you see any issues.

Thanks,
Avinash
