[PATCH RT 26/27] lockdep: selftest: fix warnings due to missing PREEMPT_RT conditionals

[Steven Rostedt]

3.4.106-rt132-rc1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Josh Cartwright <josh.cartwright@xxxxxx>

"lockdep: Selftest: Only do hardirq context test for raw spinlock"
disabled the execution of certain tests with PREEMPT_RT_FULL, but did
not prevent the tests from still being defined.  This leads to warnings
like:

  ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_12' defined but not used [-Wunused-function]
  ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_21' defined but not used [-Wunused-function]
  ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_12' defined but not used [-Wunused-function]
  ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_21' defined but not used [-Wunused-function]
  ./linux/lib/locking-selftest.c:580:1: warning: 'irqsafe1_soft_spin_12' defined but not used [-Wunused-function]
  ...

Fixed by wrapping the test definitions in #ifndef CONFIG_PREEMPT_RT_FULL
conditionals.
