net: hns3: fix rx VLAN offload state inconsistent issue



[ Upstream commit bbfd4506f962e7e6fff8f37f017154a3c3791264 ]

Currently, VF doesn't enable rx VLAN offload when initializating,
and PF does it for VFs. If user disable the rx VLAN offload for
VF with ethtool -K, and reload the VF driver, it may cause the
rx VLAN offload state being inconsistent between hardware and
software.

Fixes it by enabling rx VLAN offload when VF initializing.
