sfc: do not device_attach if a reset is pending
efx_start_all can return without initialising queues as a reset is pending.
This means that when netif_device_attach is called, the kernel can start
sending traffic without having an initialised TX queue to send to.
This patch avoids this by not calling netif_device_attach if there is a
pending reset.
Fixes: e283546c0465 ("sfc:On MCDI timeout, issue an FLR (and mark MCDI to fail-fast)")
