swrast: Remove 'inline' from tex filter functions.

Reduces .text size of mesa_dri_drivers.so (i965-only) by 62k, or 1.4%.

Note that we don't remove inline from lerp_2d(), which has a comment
above it saying it definitely should be inlined. Though, removing the
inline keyword from it doesn't actually change the compiled code for me.
