The fragment lookup should only be performed, when
at least one of the fragment flags are set.
This change was deliberately not included in commit
68aba00483c7 ("net: sparx5: flower: fix fragment flags handling")
as it's only needed for future proffing the code, since
"mask" is currently only set in conjunction with the
fragment flags.
(The 3rd flag FLOW_DIS_ENCAPSULATION is only used with "key")
Only compile tested.
