[PATCH v2] net/hns3: fix the time waiting for PF reset completion

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

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.
