Revert "i965: fix hacked Fallback usage in brw_prepare_vertices()"

This reverts commit 8810b8f67135185d1044746bb861fe2ff997626c.

It turns out the i965 driver uses the intel->Fallback field as a boolean,
not as a bitmask.  The intelFallback() function is a no-op in the i965
driver.  It would have been nice if there were some comments about this.
I'll fix that next...
