[Guillaume Martres]

ffmpeg | branch: release/2.1 | Guillaume Martres <smarter at ubuntu.com> | Sat Jan 11 22:46:25 2014 +0100| [e43805d40188f2797619cdf068b64d2c3ada8a8f] | committer: Michael Niedermayer

hevc: remove useless clip in FUNC(sao_band_filter)()

The src buffer should only contain values in the interval
[0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift
must be in the interval [0, 31], so no clip is needed.

This removes the code that was changed in 5856bca360c5bc3e340a357d91b1f993c80a7bea
as the clip that was repositioned in that commit is removed
