P2P: Cancel group formation timeout on client connection

It was possiblle for the group formation timeout to be left running even
after the P2P Client connected to the group if the WPS provisioning step
was not completed cleanly (e.g., due to WSC_Done not getting received
from the client). There is no need to remove the group in such case due
to the initial group formation timeout, so work around this by removing
that timeout on data connection.
