i965: Use atomic ops in get_new_program_id().
We have a nice utility function for this, which eliminates the need for
locking stuff. This isn't really performance critical, but it's less
code to use the atomic.
p_atomic_inc_return does pre-increment rather than post-increment, so we
change screen->program_id to be initialized to 0 instead of 1. At which
point, we can just delete the initialization because intel_screen is
rzalloc'd.
