[PATCH net v2] net: libwx: fix to enable RSS

[PATCH net v2] net: libwx: fix to enable RSS

[Jiawen Wu]

Now when SRIOV is enabled, PF with multiple queues can only receive
all packets on queue 0. This is caused by an incorrect flag judgement,
which prevents RSS from being enabled.

In fact, RSS is supported for the functions when SRIOV is enabled.
Remove the flag judgement to fix it.
