PCI/portdrv: Fix potential resource leak
[ Upstream commit 01464a3fdf91c041a381d93a1b6fefbdb819a46f ]
pcie_port_probe_service() unconditionally calls get_device() (unless it
fails). So drop that reference also unconditionally as it's fine for a
PCIe driver to not have a remove callback.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
