net/ice: distinguish input set outer fields

Distinguish input_set_mask to inner and outer part. Use
input_set_mask_o for tunnel outer or non-tunnel input set.
input_set_mask_i is used for tunnel inner fields only.

Adjust indentation of ice_pattern_match_item list in switch, ACL, RSS
and FDIR for easy review.

For switch, ACL and RSS, only use
input_set_mask_o and set the input_set_mask_i all none.
