staging: vchiq_core: Simplify bulk transfer queue message function

vchiq_bulk_xfer_queue_msg_killable() is a common function between
various bulk transfer code paths (blocking, callback and no-callback).
These code paths were simplified earlier by passing a populated
struct vchiq_bulk pointer in order to avoid open-coding the parameters
required to initiate a bulk transfer.

Now simplify the vchiq_bulk_xfer_queue_msg_killable() in a similar way
i.e. avoid open-coding the function parameters and pass the struct
vchiq_bulk pointer directly, coming from the various bulk transfer code
paths.
