ice: Introduce enabling promiscuous mode on multiple VF's

In current implementation default VSI switch filter is only able to
forward traffic to a single VSI. This limits promiscuous mode with
private flag 'vf-true-promisc-support' to a single VF. Enabling it on
the second VF won't work. Also allmulticast support doesn't seem to be
properly implemented when vf-true-promisc-support is true.

Use standard ice_add_rule_internal() function that already implements
forwarding to multiple VSI's instead of constructing AQ call manually.

Add switch filter for allmulticast mode when vf-true-promisc-support is
enabled. The same filter is added regardless of the flag - it doesn't
matter for this case.

Remove unnecessary fields in switch structure. From now on book keeping
will be done by ice_add_rule_internal().

Refactor unnecessarily passed function arguments.

To test:
1) Create 2 VM's, and two VF's. Attach VF's to VM's.
2) Enable promiscuous mode on both of them and check if
   traffic is seen on both of them.
