Reset the configuration of vlan strip that would be change
by the pf kernel driver when adding vlan from vf.
Application cannot use rte_eth_dev_set_vlan_offload() to set
the VLAN_STRIP, as this will only work for the first time when
original and current config mismatch, but for all subsequent call
it will be ignored.

v2:
* Simplied the commit log.
* goto err; is not required as it has only one more return path
and there is no cleanup required apart from just return err.
* Updated the comment start from /* -> /**
* Changed the error log in case vlan strip command fails.
