[PATCH net] iavf: iavf_virtchnl_completion: drop duplicate ether_addr_equal() test

[Corinna Vinschen]

This is just a simple cleanup fix.  Commit 35a2443d0910f ("iavf: Add
waiting for response from PF in set mac") introduced a duplicate
ether_addr_equal() check, so the current code tests the new MAC twice
against the former MAC.

Remove the outer ether_addr_equal() test, remnant of commit c5c922b3e09b
("iavf: fix MAC address setting for VFs when filter is rejected")

Hi,

This feels more like a cleanup for net-next (without a Fixes tag)
than a fix for net. I'm missing where the bug is here.
