wireless/rt2x00: don't use PREPARE_WORK in rt2800usb.c 

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.

Update rt2800usb.c to use INIT_WORK() instead of PREPARE_WORK().  As
the work item isn't in active use during rt2800usb_probe_hw(), this
doesn't cause any behavior difference.

It would probably be best to route this with other related updates
through the workqueue tree.

Only compile tested.
