PCI: pciehp: Remove useless pciehp_get_latch_status() calls
Long ago, we updated a "switch_save" field based on the latch status. But switch_save was unused, and ed6cbcf2ac70 ("[PATCH] pciehp: miscellaneous cleanups") removed it. We no longer use the latch status, so remove calls to pciehp_get_latch_status(). No functional change intended.
