net: hns3: add check for HNS3_NIC_STATE_INITED before net open

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

----------------------------

In a small chance, a VF reset failed, and the VF device was not
initialized. In the time window before it retry, if another task
calls hns3_reset_notify_up_enet(), it will access uninitialized
ring memory, and calltrace. So add check for HNS3_NIC_STATE_INITED
before calling hns3_nic_net_open() in hns3_reset_notify_up_enet().
