[ Upstream commit 60484103d5c387df49bd60de4b16c88022747048 ]

Add configuration of interrupt type and fifo interrupt enable of TM QCN
error event if enabled, otherwise this event will not be reported when
there is error.

Fixes: d914971df022 ("net: hns3: remove redundant query in hclge_config_tm_hw_err_int()")
