sparc32: Fix might-be-used-uninitialized warning in do_sparc_fault().
When we try to handle vmalloc faults, we can take a code path which uses "code" before we actually set it. Amusingly gcc-3.3 notices this yet gcc-4.x does not. Reported-by: Bob Breuer <breuerr@mc.net> Signed-off-by: David S. Miller <davem@davemloft.net>
