[dpdk-stable] [PATCH v2] net/ixgbe: fix link status

[Cui LunyuanX <lunyuanx.cui@intel.com>]

After ports reset, tx laser register will be reset. The link
status for 82599eb got from link status register was not correct.
Set tx laser disabled after ports reset.

ixgbe_dev_setup_link_alarm_handler() will set tx laser enabled
when show port information. The purpose of the function has already
implemented in ixgbe_dev_start(). There is no need to reuse it
in ixgbe_dev_link_update_share().

Fixes: 0408f47ba4d6 ("net/ixgbe: fix busy polling while fiber link update")
