David S. Miller 0f58189d4a sparc64: Make lock backoff really a NOP on UP builds. 
As noticed by Mikulas Patocka, the backoff macros don't
completely nop out for UP builds, we still get a
branch always and a delay slot nop.

Fix this by making the branch to the backoff spin loop
selective, then we can nop out the spin loop completely.
