ARB prog: Set error instead of falling through with incorrect value
If a fragment program only parameter was queried of a vertex program
(e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and
a random value would be returned. This caused 'glxinfo -l' to show
the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for
GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect.
