net/ice/base: change dummy packets with VLAN

Ethertype was traded as VLAN tpid in dummy packets with VLAN.
This led to a problem when user wanted to add filter for VLAN and
ethertype.

Change ice_vlan_hdr to reflect correct order of VLAN fields in
packets (VLAN tpid, VLAN id). Correct all dummy packets with VLAN.
Move VLAN fields before ethertype and change offsets. Leave values
from dummy packets unchanged as they fit to new VLAN layout.

Order of offsets in ice_prot_ext_tbl_entry for VLAN protocol should
reflect order of fields in ice_vlan_hdr. However, hardware doesn't
support matching on all tpid. This should be done by matching on
packet flags. There is no FV word with protocol for VLAN and offset
2. Because of that, adding vlan tpid with not zero mask will lead
to error in creating recipe.
