Since commit 8d85a7a4f2c9 ("PCI/IOV: Allow PF drivers to limit total_VFs
to 0") the meaning of pci_sriov_set_totalvfs(pdev, 0) changed from
'no limit set/can use total_VFs' to 'limit set to 0/can't use any VFs'.
The driver was resetting the limit in case different FW or driver has
set it to an incorrect value. Now the PCI core will take care of
resetting so we don't have to do that.
Fixes: 8d85a7a4f2c9 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0")
