After commit c82f63e411f1b58427c103bd95af2863b1c96dd1
(PCI: check saved state before restore) pcie_portdrv_slot_reset()
may not work correctly if dev->error_state is equal to
pci_channel_io_frozen, because dev->state_saved need not be set at
that time. Fix this issue by setting dev->state_saved before
pci_restore_state() is called in pcie_portdrv_slot_reset().
