Subject: [PATCH v17 05/12] PCI: portdrv: remove reset_link member from pcie_port_service_driver

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>

reset_link member in struct pcie_port_service_driver was
mainly added to let pcie_do_recovery() trigger the driver
specific reset_link() on PCIe fatal errors. But after
modifying the pcie_do_recovery() function to accept reset_link
callback as function parameter, we no longer have need to use
or set reset_link in struct pcie_port_service_driver. So remove
it.
