net: dsa: hellcreek: fix missing error handling in LED registration

Browse source

[ Upstream commit e6751b0b19 ]

The LED setup routine registered both led_sync_good
and led_is_gm devices without checking the return
values of led_classdev_register(). If either registration
failed, the function continued silently, leaving the
driver in a partially-initialized state and leaking
a registered LED classdev.

Add proper error handling
