PCI: Remove unnecessary check for pcie_get_mps() failure
After 59875ae489 ("PCI/core: Use PCI Express Capability accessors"), pcie_get_mps() never returns an error, so don't bother to check for it. No functional change. [bhelgaas: changelog, fix pcie_get_mps() doc] Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
