IB/hfi1: Fix hfi1_netdev_rx_init() error handling
The hfi1_vnic_up() function doesn't check whether hfi1_netdev_rx_init()
returns errors. In hfi1_vnic_init() we need to change the code to
preserve the error code instead of returning success.
Fixes: 2280740f01ae ("IB/hfi1: Virtual Network Interface Controller (VNIC) HW support")
Fixes: 4730f4a6c6b2 ("IB/hfi1: Activate the dummy netdev")
