drm/i915/dp_mst: Simplify handling the single-bpp case during state computation
A follow-up change wants to skip invalid bpps in the bpp select loop of
a stream state computation. To allow for that, using the usual
'continue' statement in the loop, change the way the single-bpp range is
handled.
v2: Fix typo in commit message. (Ankit)
