Thierry Reding b6f6d56c91 PCI: Allow PCI express root ports to find themselves
If the pci_find_pcie_root_port() function is called on a root port
itself, return the root port rather than NULL.

This effectively reverts commit 0e40523287 ("PCI: fix oops when
try to find Root Port for a PCI device") which added an extra check
that would now be redundant.

Fixes: a99b646afa ("PCI: Disable PCIe Relaxed Ordering if unsupported")
Fixes: c56d4450eb ("PCI: Turn off Request Attributes to avoid Chelsio T5 Completion erratum")
