Fix the limits for CELT_SET_END_BAND_REQUEST.

The valid bands range from [start,end) everywhere, with start<end.
Therefore end should never be 0, and should be allowed to extend
 all the way to mode->nbEBands.
This patch does _not_ enforce that start<end, and it does _not_
 handle clearing oldBandE[] when the valid range changes, which
 are separate issues.
