drm/sun4i: Fix releasing node when enumerating enpoints
[ Upstream commit 367c359aa8637b15ee8df6335c5a29b7623966ec ]
sun4i_drv_add_endpoints() has a memory leak since it uses of_node_put()
when remote is equal to NULL and does nothing when remote has a valid
pointer.
Invert the logic to fix memory leak.
