net: hns3: check resetting status in hns3_get_stats()

[ Upstream commit c4e401e5a934bb0798ebbba98e08dab129695eff ]

hns3_get_stats() should check the resetting status firstly,
since the device will be reinitialized when resetting. If the
reset has not completed, the hns3_get_stats() may access
invalid memory.
