net/mlx5: Allow 0 for total host VFs
commit 2dc2b3922d3c0f52d3a792d15dcacfbc4cc76b8f upstream. When querying eswitch functions 0 is a valid number of host VFs. After introducing ARM SRIOV falling through to getting the max value from PCI results in using the total VFs allowed on the ARM for the host. Fixes: 86eec50beaf3 ("net/mlx5: Support querying max VFs from device"); Signed-off-by: Daniel Jurgens <danielj@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
