net: hns3: check resetting status when doing VLAN ops

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

The VLAN ops should check the resetting status firstly,
since the device will be reinitialized when resetting. If the
reset has not completed, the VLAN ops may access invalid memory.
And this checking can make it return as soon as possible.
