Smatch complains that "userdata" can be passed to vchiq_bulk_transfer()
without being initialized. Smatch is correct, however, in that
situation the "userdata" is not used so it doesn't cause a problem.
Passing an uninitialized variable will trigger a UBSan warning at
runtime so this warning is worth silencing by setting "userdata" to
NULL.
