Reset sriov_numvfs to 0 before leapp upgrade

Leapp's actor persistentnetnamesconfig will try
to apply the nic names based on the mac address.
Whlie collecting the data, leapp will also add the
VFs details to RHEL7 catalog (leapp.db). But when
RHEL8 ramfs boots, it will not find the VF interfaces.
VFs will be configured using sriov_config service
on boot (not applied during upgrade). Remove VFs
before leapp upgrade as a workaround.
Closes-Bug: #1890769
