net: hns3: activate reset timer when calling reset_event

Browse Source 
When calling hclge_reset_event() within HCLGE_RESET_INTERVAL,
it returns directly now. If no one call it again, then the
error which needs a reset to fix it can not be fixed.

So this patch activates the reset timer for this case, and
adds checking in the end of the reset procedure to make this
error fixed earlier.
