glsl2: Fix transpose of rows and cols

Browse source 
This error led to an assertion failure for some constructors of
non-square matrices.  It only occured in matrices where the number of
columns was greater than the number of rows.  It didn't even always
occur on those.

Fixes piglit glslparsertest case constructor-16.vert.
