[Nouveau] [PATCH] drm/nouveau/fifo:Fix Nineteen occurrences of the gk104.c error: ERROR: : trailing statements should be on next line

NAK - checkpatch.pl is a (strongish) guideline, but not a rule. In the cases
corrected in the patch series here, we format the switch cases on single lines
as it dramatically improves the readability of what is otherwise just a /long/
list of slightly different static mappings. I don't believe we're the
only
part of the kernel to do this either.

This one isn't very long, but I'd still say it's definitely a lot
easier to
read in the compact form. If anything, the only change I would make here is
formatting the default: case to be on a single line as well
