[PATCH net-next V2 3/5] qeth: move OSA portname into deprecated status

[Ursula Braun <ubraun@linux.vnet.ibm.com>]

From: Ursula Braun <ursula.braun@de.ibm.com>

An OSA-Express port name was required to identify a shared OSA port.
All operating system instances that shared the port had to use the
same port name. This requirement no longer applies.
