futex: Move futex_queue() into futex_wait_setup()

Browse source

futex_wait_setup() has a weird calling convention in order to return
hb to use as an argument to futex_queue().

Mostly such that requeue can have an extra test in between.

Reorder code a little to get rid of this and keep the hb usage inside
futex_wait_setup().
