Revert "mesa: do not trigger _NEW_TEXTURE_STATE in glActiveTexture()"

This reverts commit f314a532.

This appears to introduce some blinking textures in UT2004. Not
sure exactly what's the root cause because we don't have much
information about the issue.

Anyway, this was just a micro optimization that actually breaks,
at least, one app almost one year later.
