PCI: keystone: Fix OF node reference leak in init

Browse source

of_find_matching_node() returns a device node with its reference count
incremented. ks_pcie_init() only uses the returned node to decide whether
to register the ARM external abort fault handler, but never drops the
reference.

Store the lookup result in a temporary variable and release it with
of_node_put() once the existence check has been made.
