tipc: relocate common functions from media to bearer
Currently, registering a TIPC stack handler in the network device layer is done twice, once for Ethernet (eth_media) and Infiniband (ib_media) repectively. But, as this registration is not media specific, we can avoid some code duplication by moving the registering function to the generic bearer layer, to the file bearer.c, and call it only once. The same is true for the network device event notifier. As a side effect, the two workqueues we are using for for setting up/ cleaning up media can now be eliminated. Furthermore, the array for storing the specific media type structs, media_array[], can be entirely deleted. Note that the eth_started and ib_started flags were removed during the code relocation. There is now only one call to bearer_setup and bearer_cleanup, and these can logically not race against each other. Despite its size, this cleanup work incurs no functional changes in TIPC. In particular, it should be noted that the sequence ordering of received packets is unaffected by this change, since packet reception never was subject to any work queue handling in the first place.
