[Piglit] [PATCH 1/2] glsl-max-varyings: Clean up max_varyings misnomer.

[Paul Berry]

In glsl-max-varyings' draw() function, the parameter max_varyings
actually represented the number of varyings to test, not the maximum.
Renamed to num_varyings, in accordance with the name of this parameter
in get_vs() and get_fs().
