staging: vchiq_core: Simplify vchiq_bulk_transfer()

Browse source

Factor out core logic for preparing bulk data transfer(mutex locking,
waits on vchiq_bulk_queue wait-queue, initialising the bulk transfer)
out of the vchiq_bulk_transfer(). This simplifies the existing
vchiq_bulk_transfer() and makes it more readable since all the core
logic is handled in vchiq_bulk_xfer_queue_msg_interruptible(). It
will also help us to refactor vchiq_bulk_transfer() easily for different
vchiq bulk transfer modes.
