[PATCH] wpa_supplicant: Added newline to the pin string printed to the user

[Guy Eilam]

Added a newline at the end of the pin string for both
generated pin and given pin from the user.
In case the user runs the "wps pin" command from inside
the cli, the pin number printed to the user might be
erased after less then a second by the following messages in
the connection process when there is no newline.
