lib/string_helpers: fix not adding strarray to device's resource list

commit cd290a9839cee2f6641558877e707bd373c8f6f1 upstream.

Add allocated strarray to device's resource list. This is a must to
automatically release strarray when the device disappears.

Without this fix we have a memory leak in the few drivers which use
devm_kasprintf_strarray().
