When stress testing the kernel using the syzkaller the following
warning occurs frequently:

[ 553.403826] 001: complete_all() with 4 waiters
[ 553.404205] 001: WARNING: CPU: 1 PID: 10418 at swake_up_all_locked+0x146/0x1e0
[ 553.404806] 001: Modules linked in:
[ 553.405101] 001:
[ 553.405269] 001: CPU: 1 PID: 10418 Comm: cryptomgr_probe Tainted: G

Investigation shows that this warning is caused due to the mode
of working of the crypto module using completions. The increased number
was found through experimentaion using syzkaller.
