iio: ssp_sensors: fix error code in ssp_print_mcu_debug()
commit 4170d3dd1467e9d78cb9af374b19357dc324b328 upstream.
The ssp_print_mcu_debug() function should return negative error codes on
error. Returning "length" is meaningless. This change does not affect
runtime because the callers only care about zero/non-zero.
