crypto: sun8i-ss - call finalize with bh disabled
[ Upstream commit b169b3766242b6f3336e24a6c8ee1522978b57a7 ]
Doing ipsec produces a spinlock recursion warning.
This is due to not disabling BH during crypto completion function.
Fixes: f08fcced6d00 ("crypto: allwinner - Add sun8i-ss cryptographic offloader")
