[SRU][P][PATCH v2 4/6] UBUNTU: SAUCE: gpio: aggregator: Fix error code in gpio_aggregator_activate()

[Koichiro Den]

From: Dan Carpenter <dan.carpenter at linaro.org>

BugLink: https://bugs.launchpad.net/bugs/2103496

Propagate the error code if gpio_aggregator_make_device_sw_node() fails.
Don't return success.
