slcan: remove obsolete code in slcan initialisation
This patch removes obsolete code in the initialisation/creation of
slcan devices.
It follows the suggested cleanups from Ilya Matvejchikov in
drivers/net/slip.c that where recently applied to net-next-2.6:
- slip: remove dead code within the slip initialization
- slip: remove redundant check slip_devs for NULL
