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")

I think Cc: stable@vger.kernel.org should be added.
