net/hns3: increase time waiting for PF reset completion

On the case that PF and VF need to be reset, after the hardware reset is
complete, VF needs wait for 1 second to restore the configuration so
that VF does not fail to recover because PF reset isn't complete. But
the estimated time is not sufficient. This patch fixes it to 5 seconds.
