i965 VS: Change nr_userclip to nr_userclip_planes.
The only remaining uses of brw_vs_prog_key::nr_userclip only occurred
when using clip planes (as opposed to gl_ClipDistance). This patch
renames the value to nr_userclip_planes and sets it to zero when
gl_ClipDistance is in use. This avoids unnecessary VS recompiles.
