net/ice/base: support removing VSI from flow profile

Browse Source 
Adding a function ice_flow_rem_vsi_prof() to remove flow entries
associated to the SW VSI handle. Once complete, clear the vsi index from
the flow profile bitmap. This will ensure that a VSI once removed
can be re-added and the package block rules will be added again.
