sched/wait: Re-adjust macro line continuation backslashes in <linux/wait.h>
So there's over 300 CPP macro line-continuation backslashes in include/linux/wait.h (!!), which are aligned vertically to make the macro maze a bit more navigable. The recent renames and reorganization broke some of them, and instead of re-aligning them in every patch (which would add a lot of stylistic noise to the patches and make them less readable), I just ignored them - and fixed them up in a single go in this patch.
