Weigang He 81122fba08 of: fix reference count leak in of_alias_scan()
of_find_node_by_path() returns a device_node with its refcount
incremented. When kstrtoint() fails or dt_alloc() fails, the function
continues to the next iteration without calling of_node_put(), causing
a reference count leak.

Add of_node_put(np) before continue on both error paths to properly
release the device_node reference.

Fixes: 611cad7201 ("dt: add of_alias_scan and of_alias_get_id")
