[PATCH -rt] harirq.h: Define softirq_count() as OUL to kill build warning

[Yong Zhang <yong.zhang0@gmail.com>]

kernel/lockdep.c: In function ‘print_bad_irq_dependency’:
kernel/lockdep.c:1476:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 7 has type ‘unsigned int’
kernel/lockdep.c: In function ‘print_usage_bug’:
kernel/lockdep.c:2193:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 7 has type ‘unsigned int’

kernel/lockdep.i show this:
 printk("%s/%d [HC%u[%lu]:SC%u[%lu]:HE%u:SE%u] is trying to acquire:\n",
  curr->comm, task_pid_nr(curr),
  curr->hardirq_context, ((current_thread_info()->preempt_count) & (((1UL << (10))-1) << ((0 + 8) + 8))) >> ((0 + 8) + 8),
  curr->softirq_context, (0U) >> (0 + 8),
  curr->hardirqs_enabled,
  curr->softirqs_enabled);
