[PATCH NEXT 6/6] PCI/PORTDRV: Remove ERR_FATAL handling from pcie_portdrv_slot_reset()

[Oza Pawandeep <poza@codeaurora.org>]

We are handling ERR_FATAL by resetting the Link in software,skipping the
driver pci_error_handlers callbacks, removing the devices from the PCI
subsystem, and re-enumerating, as a result of that, no more calling
pcie_portdrv_slot_reset in ERR_FATAL case.
