Fix qla2xxx fabric's HBA detection to be more inclusive

Initial attempt looking for symbolic_name starting with "QMI2" was not
right, since other supported adapters don't start with that.

Expand the heuristic - if it's not FCoE, it must be qla. Still a little
loose but it works for now.

Closes #25
