[PATCH] test/crypto: fix output buffer length

[Gagandeep Singh]

Input buffer length is getting appended with
padding length when the test case is encrypted
digest, but output buffer length is appended
with padding length for all the cases.

This patch fixes the output buffer length
by appending the padding length only when the
test case is of encrypted digest type.

Fixes: 6356c28642a6 ("test/crypto: add cases for block cipher encrypted digest")
