net: hns3: clear restting state when initializing HW device

IMP will set restting state for all function when PF FLR, driver
just clear the restting state in resetting progress, but don't do
it in initializing progress. As FLR is not created by driver,
it is necessary to clear restting state when initializing HW device.
