net/ice/base: fix duplicate flow rules

Browse Source 
When a vsi that already exists in the created vsi_list subscribes to the
same filter again, the return value ICE_SUCCESS results in duplicate flow
rules to be stored, which will cause 'flush' and 'destroy' errors.

Fixes: fed0c5ca5f ("net/ice/base: support programming a new switch recipe")
