i965: Fix missing CACHE_NEW_WM_PROG in 3DSTATE_PS_EXTRA.

brw->wm.prog_data is covered by CACHE_NEW_WM_PROG, not
BRW_NEW_FRAGMENT_PROGRAM.  So, we should listen to it.

However, I believe that BRW_NEW_FRAGMENT_PROGRAM is sufficient to cover
all the necessary cases - CACHE_NEW_WM_PROG happens in a subset of
cases.  So, the code being wrong shouldn't have triggered bugs.
