[PATCH] rt-mutex: fixup rt-mutex debug code
BUG: warning at kernel/rtmutex-debug.c:125/rt_mutex_debug_task_free() (Not tainted)

In copy_process(), dup_task_struct() also duplicates the ->pi_lock,
->pi_waiters and ->pi_blocked_on members. rt_mutex_debug_task_free()
called from free_task() validates these members. However free_task() can
be invoked before these members are reset for the new task.
Move the initialization code before the first bail that can hit free_task().
