[Adam] OK, will do in v2.

[Adam] Few negative tests had to be updated because now in the case of any
op error, the process request function returns NULL. The negative tests now check
for the NULL instead of checking for nonzero op status. This was done in
test_authenticated_decryption_fail_when_corruption, test_authentication_verify_GMAC_fail_when_corruption and test_authentication_verify_fail_when_data_corruption.
