platform/chrome: cros_ec_typec: fix missing fwnode reference decrement

BugLink: https://bugs.launchpad.net/bugs/2101915

commit 9c41f371457bd9a24874e3c7934d9745e87fbc58 upstream.

The device_for_each_child_node() macro requires explicit calls to
fwnode_handle_put() upon early exits (return, break, goto) to decrement
the fwnode's refcount, and avoid levaing a node reference behind.

Add the missing fwnode_handle_put() after the common label for all error
paths.
