crypto: tcrypt - fix S/G table for test_aead_speed()
In case buffer length is a multiple of PAGE_SIZE, the S/G table is incorrectly generated. Fix this by handling buflen = k * PAGE_SIZE separately. Signed-off-by: Robert Baronescu <robert.baronescu@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
