scsi: megaraid_sas: Enable msix_load_balance for Invader and later controllers
Load balancing IO completions across all available MSI-X vectors should be
enabled for Invader and later generation controllers only. This needs to
be disabled for older controllers. Add an adapter type check before
setting msix_load_balance flag.
