llvmpipe: restore call to lp_setup_update_state()

This undoes part of commit 8be645d53a0d5d0ca50e4e9597043225e2231b6d
and fixes fd.o bug 28822 as well as other regressions.

The 'draw' module may issue additional state-change commands while
we're inside the draw_arrays/elements() call so it's important to
check for updated state at this point.
