[PATCH] CompactPCI: remove two useless checks

This two checks are useless: cpci_hp_register_bus is only called from two
places, one has constant arguments, the other one passes the module
parameters which are checked for this condition on module load. And the bus
argument of cpci_hp_unregister_bus can never be NULL, all functions calling
this function use fields of the bus struct before so they will oops if it
would ever be NULL.
