qla2xxx: Disable MSI on qla24xx chips other than QLA2432.
commit 6377a7ae1ab82859edccdbc8eaea63782efb134d upstream.
On specific platforms, MSI is unreliable on some of the QLA24xx chips, resulting
in fatal I/O errors under load, as reported in <http://bugs.debian.org/572322>
and by some RHEL customers.
