Correct fence pitch checking code and fence register writing on 9{1,4}x.

The tiling check was insufficient and allowing too large pitches, which
in some cases could cause graphical corruption, strengthen the check so
that only valid values are used. Solved and patch ported from one by
Daniel Vetter on intel-gfx.

tested by Dorian Buettner (first dot last @ gmx dot de); thanks!
