[PATCH] sched: remove outdated/misleading comments

This patch removes two outdated/misleading comments from the CPU scheduler.

1) The first comment removed is simply incorrect.  The function it
   comments on is not used for what the comments says it is anymore.

2) The second comment is a leftover from when the "if" block it comments
   on contained a goto.  It does not any more, and the comment doesn't make
   sense.

There isn't really a reason to add different comments, though someone might
feel differently in the case of the second one.  I'll leave adding a
comment to anybody who wants to - more important to just get rid of them
now.
