NEC driver: initialize_connection() returns random information.

[Shunei Shiono]

The method initialize_connection() in NEC driver returns
a set of randomly selected FC/iSCSI portals available.
However, the method should return the same set of ports every time
because it may be called multiple times to get connection information
after a voluem has already been attached.
