From: Corentin Labbe <clabbe@baylibre.com>

[ Upstream commit dba633342994ce47d347bcf5522ba28301247b79 ]

Doing ipsec produces a spinlock recursion warning.
This is due to not disabling BH during crypto completion function.

Fixes: 48fe583fe541 ("crypto: amlogic - Add crypto accelerator for amlogic GXL")
