crypto: sun8i-ss - Fix a test in sun8i_ss_setup_ivs()
[ Upstream commit 8fd91151ebcb21b3f2f2bf158ac6092192550b2b ]
SS_ENCRYPTION is (0 << 7 = 0), so the test can never be true.
Use a direct comparison to SS_ENCRYPTION instead.
The same king of test is already done the same way in sun8i_ss_run_task().
