scsi: megaraid_sas: enable intx only if msix request fails
Without this fix, driver will enable INTx Interrupt pin even though
MSI-x vectors are enabled. See below lspci output. DisINTx is unset for
MSIx setup.

After applying this fix, driver will enable INTx Interrupt pin only if
Legacy interrupt method is required. See below lspci output. DisINTx is
set for MSIx setup. lspci -s 85:00.0 -vvv |grep INT |grep Control
