soc: qcom: pmic: Fix resource leaks in a device_for_each_child_node() loop

[ Upstream commit 5692aeea5bcb9331e956628c3bc8fc9afcc9765d ]

The device_for_each_child_node loop should call fwnode_handle_put()
before return in the error cases, to avoid resource leaks.

Let's fix this bug in pmic_glink_altmode_probe().
