... by not incorrectly hinting to the compiler the function argument of
cipher_kt_mode_{cbc,ofb_cfb}() is nonnull, since that no longer is the
case.
Verified the fix on Debian Wheezy, one of the platforms the reporter in
trac #473 mentions with a compiler that would optimize out the required
checks.
Also add a testcase for --cipher none to t_lpback, to prevent further
regressions.
