Back in 2017, commit 2fd260f03b ("PCI/AER: Remove unused .link_reset()
callback") removed .link_reset() from struct pci_error_handlers, but left
a few code comments behind which still mention it. Remove them.
The code comments in the SolarFlare Ethernet drivers point out that no
.mmio_enabled() callback is needed because the driver's .error_detected()
callback always returns PCI_ERS_RESULT_NEED_RESET, which causes
pcie_do_recovery() to skip .mmio_enabled(). That's not quite correct
because efx_io_error_detected() does return PCI_ERS_RESULT_RECOVERED under
certain conditions and then .mmio_enabled() would indeed be called if it
were implemented. Remove this misleading portion of the code comment as
well.
