The macro flag DEV_RX_OFFLOAD_VLAN_FILTER is used to enable/disable
Rx VLAN filter, but not Tx VLAN filter. Therefore, Tx VLAN filter
should not be enabled/disabled in function ice_vsi_config_vlan_filter
called after checking DEV_RX_OFFLOAD_VLAN_FILTER flag.
In addition, the kernel driver doesn't enable/disable the TX VLAN
filter in the similar function ice_cfg_vlan_pruning.
This patch removes the setting about the TX VLAN filter in function
ice_vsi_config_vlan_filter.
