mesa: fix texture target mix-up in NV_fragment_program parser

The returned value should be a texture target index, not a bit.
I spotted this from seeing a new compiler warning caused by the increase
in the number of texture targets.  This has been broken for a long time.

Note: This is a candidate for the 7.11 branch.
