Zqiang b5cc577751 lib: stackdepot: turn depot_lock spinlock to raw_spinlock 
[ Upstream commit 78564b9434878d686c5f88c4488b20cccbcc42bc ]

In RT system, the spin_lock will be replaced by sleepable rt_mutex lock,
in __call_rcu(), disable interrupts before calling
kasan_record_aux_stack(), will trigger this calltrace:

  BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:951
  in_atomic(): 0, irqs_disabled(): 1, non_block: 0, pid: 19, name: pgdatinit0
  Call Trace:

    rt_spin_lock+0x3b/0xb0
    stack_depot_save+0x1b9/0x440

Replace spinlock with raw_spinlock.
