macvtap: fix the missing ret value of TUNSETQUEUE
Commit 441ac0fcaadc76ad09771812382345001dd2b813 (macvtap: Convert to using rtnl lock) forget to return what macvtap_ioctl_set_queue() returns to its caller. This may break multiqueue API by always falling through to TUNGETFEATURES. Cc: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
