Subject: [PATCH] component: do not stop components lookup after first fail

Currently showing content of /sys/kernel/debug/device_component/*
works partially, in case one of the components is not available this and
all remaining components have status not-registered, but the problem
is only with the first one.
Allowing to finish lookup for other components in case one is missing
solves the issue.
