[dpdk-dev] [PATCH 24/26] ixgbe/base: set lan_id before first I2C access

[Wenzhuo Lu <wenzhuo.lu@intel.com>]

Set the lan_id before the first I2C access. The existing call was
clearly being done after a previous I2C access in the same function
and that can't be right, so call the set_lan_id method earlier. At
this point it probably doesn't matter for this QSFP function, but
it makes sense to do it consistently anyway.

On X550, be sure to set the lan_id before using it to configure the
mux control output, else the mux will not be controlled.
