[PATCH 2/4] megaraid_sas: Enable msix_load_balance for Invader and later controllers

[Shivasharan S]

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.

Fixes: 1d15d9098ad1 ("scsi: megaraid_sas: Load balance completions across all 
MSI-X")
