rcu: Remove CONFIG_PROVE_RCU_DELAY
The CONFIG_PROVE_RCU_DELAY Kconfig parameter doesn't appear to be very effective at finding race conditions, so this commit removes it. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Andi Kleen <ak@linux.intel.com> [ paulmck: Remove definition and uses as noted by Paul Bolle. ]
