ixgbe: prevent from unwanted interface name changes

ixgbe: prevent from unwanted interface name changes

Users of the ixgbe driver report that after adding devlink support by
the commit a0285236ab93 ("ixgbe: add initial devlink support") their
configs got broken due to unwanted changes of interface names. It's
caused by automatic phys_port_name generation during devlink port
initialization flow.

To prevent from that set no_phys_port_name flag for ixgbe devlink ports.
