ps3-vuart: don't use PREPARE_WORK
PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. ps3_vuart wasn't overriding the work item with multiple work functions but was using NULL for INIT_WORK() and then single PREPARE_WORK() to set the work function. We can simply invoke INIT_WORK() with the work function and remove the PREPARE_WORK() usage. It would probably be best to route this with other related updates through the workqueue tree.
