net: hns3: fix for updating fc_mode_last_time
commit a9c782822166 ("net: hns3: add support for set_pauseparam")
adds set_pauseparam support for ethtool cmd, but forgets to update
fc_mode_last_time when PFC mode is disabled in hclge_cfg_pauseparam().
The wrong fc_mode_last_time will be used to update flow control mode
when lldpad has been running. As a result, when using the ethtool
command "-a", user will get a wrong pause parameter.
This patch adds the fc_mode_last_time update when PFC mode is disabled.
