crypto: engine - check if BH is disabled during completion
[ Upstream commit 4058cf08945c18a6de193f4118fd05d83d3d4285 ]
When doing iperf over ipsec with crypto hardware sun8i-ce, I hit some
spinlock recursion bug.
This is due to completion function called with enabled BH.
Add check a to detect this.
