Merge branch 'tipc'

====================
tipc: clean up components initialization code

In this series, we will fix a regression issue involved by commit
6e967adf(tipc: relocate common functions from media to bearer)
But before the issue is fixed, we firstly adjust the process of
components initialization so as to remove all enabled flags from
necessary tipc components. Otherwise, without the change, we also
have to add an extra enabled flag into bearer layer indicating
whether bearer setup is finshed or not.
