i40e: drop is_vf and is_netdev fields in struct i40e_mac_filter

Originally the is_vf and is_netdev fields were added in order to
distinguish between VF and netdev filters in a single VSI. However, it
can be noted that we use separate VSI for SRIOV VFs and for netdev VSI.
Thus, since a single VSI should only ever have one type of filter, we
can simply remove the checks and remove the typing.

In a similar fashion, we can note that the only remaining way to get
multiple filters of a single type is through a debug command that was
added to debugfs. This command is useless in practice, and results in
causing bugs if we keep counter tracking but lose the is_vf and
is_netdev protections as desired above.

Since the only time we'd actually have a counter value besides 0 and
1 is through use of this debugfs hook, we can remove this unnecessary
command, and the entire counter logic it required.

We vastly simplify mac filters by removing

(a) the distinction between VF and netdev filters
(b) counting logic
(c) the ability to add and remove filters bypassing the stack via debugfs
