Fix calling (and checking) the decal_ functions when the input is SkFractionalInt.
The bug was to cast to SkFixed from SkFractionalInt, when what we needed to do
was shift the fractional guy down to fixed.

This bug was only caught on an android device w/o neon, since other configs have
assembly for their matrixproc that didn't have this bug.
