net: hns3: modify hclge_func_reset_sync_vf()'s return type to void

When synchronizes with VFs fail before PF function reset,
PF driver should go on its function reset, otherwise it
can not run normally anymore. So, hclge_func_reset_sync_vf()
should not affect the processing of PF reset, this patch
modifies its return type to void.
