comctl32: trackbar: Correctly set lSetMin and lSelMax.

Modify the behavior when the messages TBM_SETSEL, TBM_SETSELSTART, and
TBM_SETSELEND are sent and TBS_ENABLESELRANGE is not set.  When the
style TBS_ENABLESELRANGE is not set, Windows observed behavior is to
set the Selection Start and End values to 0, rather than leave them
unchanged.
