crypto: authenc - Fix zero-length IV crash
As it is if an algorithm with a zero-length IV is used (e.g.,
NULL encryption) with authenc, authenc may generate an SG entry
of length zero, which will trigger a BUG check in the hash layer.
This patch fixes it by skipping the IV SG generation if the IV
size is zero.
