Fix 3PAR driver hang on SSH calls

In removing the 3PAR driver local file locks, part of the fix included
making a new SSH connection for each call in the hp3parclient as
oppose to leaving a connection open. Older hp3parclients(3.1.1 and
later) will result in the SSH calls hanging at driver initilization time.

This patch will now check against the correct minimum hp3parclient version
and remove the need for checking of the SSH args version since the minimum
hp3parclient is now greater than 3.1.1
