[PATCH 1/6] qla2xxx: fix RSCN handling on big-endian systems

[Andrew Vasquez <andrew.vasquez@qlogic.com>]

From: malahal@us.ibm.com <malahal@us.ibm.com>

qla2xxx driver fails to handle RSCN events affecting area or domain due
to an endian issue on big endian systems.  This fixes the port_id_t
structure on big endian systems.
