net/ice/base: add inner VLAN protocol type for QinQ filter

Since VLAN protocol type 'ICE_VLAN_OFOS' has been changed to map
the hardware VLAN protocol ID to 'ICE_VLAN_OF_HW (16)' when in Double
VLAN mode, and to 'ICE_VLAN_OL_HW (17)' when in Single VLAN mode.

So 'ICE_VLAN_OFOS' can't be used with 'ICE_VLAN_EX' which is outer VLAN
hardware protocol ID 'ICE_VLAN_OF_HW (16)' to do the QinQ VLAN pattern.

Introduce the new inner VLAN protocol type 'ICE_VLAN_IN', which is inner
VLAN hardware protocol ID 'ICE_VLAN_OL_HW (17)'.

Now for QinQ VLAN pattern, the protocol 'ICE_VLAN_EX' and 'ICE_VLAN_IN'
should be used to set the related protocol header fields like VLAN ID.
