Sink device not displaying PIN when connect using WPS_KEYPAD option

Sink device is not displaying PIN when trying to connect from source
using WPS_KEYPAD connection option. The code for displaying PIN was
missing in Process message for the event P2P_PROV_DISC_SHOW_PIN_EVENT
in WifiServiceImpl file. Added code for the same.
