Nouveau - Dec 2013 - [PATCH] nv50: report 15 max inputs for fragment programs

First off, nv50_program only has 16 in/out varyings. However reporting
16 makes 'm' become 68 in nv50_fp_linkage_validate with the
varying-packing-simple piglit test. (Subverting the assert makes it
compile but fail.) With this patch, varying-packing-simple passes.
