Noa Osherovich 1600f62534 PCI: Support INTx masking on ConnectX-4 with firmware x.14.1100+ 
Mellanox devices were marked as having INTx masking ability broken.  As a
result, the VFIO driver fails to start when more than one device function
is passed-through to a VM if both have the same INTx pin.

Prior to Connect-IB, Mellanox devices exposed to the operating system one
PCI function per all ports.  Starting from Connect-IB, the devices are
function-per-port.  When passing the second function to a VM, VFIO will
fail to start.

Exclude ConnectX-4, ConnectX4-Lx and Connect-IB from the list of Mellanox
devices marked as having broken INTx masking:

- ConnectX-4 and ConnectX4-LX firmware version is checked. If INTx
  masking is supported, we unmark the broken INTx masking.
- Connect-IB does not support INTx currently so will not cause any
  problem.

[bhelgaas: call pci_disable_device() always, after iounmap()]
Fixes: 11e42532ad ("PCI: Assume all Mellanox devices have broken INTx masking")
