Subject: [PATCH] liquidio: style:  Identical condition and return expression  'retval', return value is always 0.

The warning was because of the following line in function
liquidio_set_fec():

retval = wait_for_sc_completion_timeout(oct, sc, 0);
    if (retval)
	return (-EIO);

If this statement is not true, retval must be 0 and not updated
later. So, It is better to return 0 directly.
