Subject: [PATCH] Return 'ghost' state when port is in standby

Currently, issuing a TUR command on a path in standby
mode, it returns a Unit Attention status. This is
reported as a Failed path by the SLES11 tur checker.
Instead, this has to be reported as Ghost path based
on the additional sense code and sense code qualifier values.
