qmi_wwan: Do not call netif_rx from rx_fixup
When the QMI_WWAN_FLAG_PASS_THROUGH is set, netif_rx() is called from
qmi_wwan_rx_fixup(). When the call to netif_rx() is successful (which is
most of the time), usbnet_skb_return() is called (from rx_process()).
usbnet_skb_return() will then call netif_rx() a second time for the same
skb.
Simplify the code and avoid the redundant netif_rx() call by changing
qmi_wwan_rx_fixup() to always return 1 when QMI_WWAN_FLAG_PASS_THROUGH
is set. We then leave it up to the existing infrastructure to call
netif_rx().
