[PATCH] fix test_and_change_bit comment

From: Paul Jackson <pj@sgi.com>

I've read over the code in each case, built and ran a test case for i386 in
particular, and studied the other uses and definitions of
test_and_change_bit().  Everything I see recommends this change.

- Fix test_and_change_bit() comment: returns old value, not new one.
