3PAR drivers are logging version numbers a lot

[Walt Boring]

When the 3PAR drivers were refactored to remove the local file locks, the login mechanism to create the client to talk to the array, has the artifact of logging the 3par common version and the client version on every driver entry point.

The driver should only be logging that information at volume manager init_host time. Not every driver entry point.

    3PAR don't log version numbers every stats update

    After the 3PAR drivers were refactored to remove the local
    file locks, the login mechanism was logging the common and
    client version numbers on every driver entry point.

    This patch removes that logging except at driver startup.
