Jakub Kicinski 83235822b8 nfp: stop limiting VFs to 0 
Before 8d85a7a4f2 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0"),
pci_sriov_set_totalvfs(pdev, 0) meant "we can enable TotalVFs virtual
functions".  After 8d85a7a4f2, it means "we can't enable *any* VFs".

That broke this scenario where nfp intends to remove any limit on the
number of VFs that can be enabled:

  nfp_pci_probe
    nfp_pcie_sriov_read_nfd_limit
      nfp_rtsym_read_le("nfd_vf_cfg_max_vfs", &err)
      pci_sriov_set_totalvfs(pf->pdev, 0)   # if FW didn't expose a limit

  ...
  # userspace writes N to sysfs "sriov_numvfs":
  sriov_numvfs_store
    pci_sriov_get_totalvfs                  # now returns 0
    return -ERANGE

Prior to 8d85a7a4f2, pci_sriov_get_totalvfs() returned TotalVFs, but it
now returns 0.

Remove the pci_sriov_set_totalvfs(pdev, 0) calls so we don't limit the
number of VFs that can be enabled.

Fixes: 8d85a7a4f2 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0")
