net: hns3: Fix for reset_level default assignment probelm
handle->reset_level is assigned to HNAE3_NONE_RESET when client is initialized, if a tx timeout happens right after initialization, then handle->reset_level is not resetted to HNAE3_FUNC_RESET in hclge_reset_event, which will cause reset event not properly handled problem. This patch fixes it by setting handle->reset_level properly when client is initialized.
