pbs-tape: sgutils2: check sense data when status is 'CHECK_CONDITION'

Some raid controllers return a 'transport error' when we expected a
'sense error'. it seems the correct way to check the sense data is when
either the result category is 'SENSE' or when the status is 'CHECK_CONDITION',
so do that. (similar to how 'sg_raw' returns the errors)
