[PATCH 2/3] s390/pci: remove unused bus_next field from struct zpci_dev

This field was added in commit 44510d6fa0c0 ("s390/pci: Handling
multifunctions") but is an unused remnant of an earlier version where
the the devices on the virtual bus were connected in a linked list
instead of a fixed 256 entry array of pointers.

It is also not used for the list of busses as that is threaded through
struct zpci_bus not through struct zpci_dev.
