mesa/readpix: Clip ReadPixels() area to the ReadBuffer's
The fast path for Intel's ReadPixels() unintentionally omits clipping
the specified area to a valid one. Rather than clip in various
corner-cases, perform this operation in the API validation stage.
The bug in intel_readpixels_tiled_memcpy() showed itself when the winsys
ReadBuffer's height was smaller than the one specified by ReadPixels().
yoffset became negative, which was an invalid input for tiled_to_linear().
v2: Move clipping to validation stage (Jason)
