[PATCH] crypto: arm/aes-neonbs Use PTR_ERR_OR_ZERO()

[Vasyl Gomonovych]

Fix ptr_ret.cocci warnings:
arch/arm/crypto/aes-neonbs-glue.c:184:1-3: WARNING: PTR_ERR_OR_ZERO can be used
arch/arm/crypto/aes-neonbs-glue.c:261:1-3: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR
