Andrey Ryabinin 79b25b1a58 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
(&xfs_nondir_ilock_class){++++}-{4:4}, at: xfs_reclaim_inode+0x3ac/0x590
[xfs]

 but task is already holding lock:
 ffffffff8bb33100 (fs_reclaim){+.+.}-{0:0}, at:
balance_pgdat+0x5d9/0xad0

 which lock already depends on the new lock.
