The MOD_INC and MOD_DEC in lapb are no longer necessary in 2.6 since
the module subsystem will not allow lapb to be unloaded as long as a module
that is referencing the symbols (lapb_register/lapb_unregister) is loaded.
The lapb parameter block does have callback's so it is up to the caller
to correctly unregister on module exit; and looking at the existing code
it does do that.
Patch is against 2.6-test1

Without an exit routine lapb can't be unloaded.
Tested on 2.6.0-test1
