Andrey Ryabinin 7d3996c74c stackdepot: respect __GFP_NOLOCKDEP allocation flag 
commit 6fe60465e1d53ea321ee909be26d97529e8f746c upstream.

If stack_depot_save_flags() allocates memory it always drops
__GFP_NOLOCKDEP flag.  So when KASAN tries to track __GFP_NOLOCKDEP
allocation we may end up with lockdep splat like bellow:

======================================================
 WARNING: possible circular locking dependency detected
 6.9.0-rc3+ #49 Not tainted
 ------------------------------------------------------
 kswapd0/149 is trying to acquire lock:
 ffff88811346a920

 but task is already holding lock:

 which lock already depends on the new lock.
