Yang Yingliang e75485fc58 device property: fix of node refcount leak in fwnode_graph_get_next_endpoint()
[ Upstream commit 39af728649 ]

The 'parent' returned by fwnode_graph_get_port_parent()
with refcount incremented when 'prev' is not NULL, it
needs be put when finish using it.

Because the parent is const, introduce a new variable to
store the returned fwnode, then put it before returning
from fwnode_graph_get_next_endpoint().

Fixes: b5b41ab6b0 ("device property: Check fwnode->secondary in fwnode_graph_get_next_endpoint()")
