net: stmmac: Do not advertise S-VLAN stripping when it is disabled

Browse source 
C-VLAN and S-VLAN tag stripping are both controlled by the EVLS bit,
so disabling rx-vlan-offload also disables S-VLAN tag stripping.
However, rx-vlan-stag-hw-parse keeps being advertised as enabled:

root@rzv2h-evk:~# ethtool -K end1 rx-vlan-offload off
root@rzv2h-evk:~# ethtool -k end1 | grep -i vlan
rx-vlan-offload: off
tx-vlan-offload: off [fixed]
rx-vlan-filter: on [fixed]
vlan-challenged: off [fixed]
tx-vlan-stag-hw-insert: off [fixed]
rx-vlan-stag-hw-parse: on [fixed]
rx-vlan-stag-filter: on [fixed]

Fix this inconsistency by making NETIF_F_HW_VLAN_STAG_RX follow
NETIF_F_HW_VLAN_CTAG_RX.
