As the err value is not used unless there was an error it can be assigned
conditionally here.

Not sure if this is really relevant and worth changing, effectively it
is practically no change as gcc would move the err = PTR_ERR(simd);
below unregister_simds: anyway (based on inspection of .lst/.s files)
- so it is more of an adjust C-level to object level for readability.
Patch was compile-tested with multi_v7_defconfig
(implies CONFIG_CRYPTO_AES_ARM_CE=m)
Patch is against 4.10-rc7 (localversion-next is next-20170208)
