[PATCH] staging: fsl-mc/dpio: Propagate error code

dpaa2_io_service_register() returns zero even if qbman_swp_CDAN_set() encountered an error. Fix this by propagating the error code so the caller is informed data availability notifications are not properly set for a channel. Signed-off-by: Ioana Radulescu ---
