iscsitarget: Fix call trace of ahash API calling
The previous build_with_updated_interfaces_of_linux_v4.8_and_above.patch
does not alloc struct ahash_request before using it. This will cause the
kernel call trace below when calling gen_scsiid on kernel 4.8 or later
version.
This patch normalizes the calling of ahash API according to the example
in kernel doc Documentation/crypto/api-intro.txt.
