This reverts commit e38030f3ff02684eb9e25e983a03ad318a10a2ea.

MSI flat-out doesn't work right on cx2388x devices yet. There are now
multiple reports of cards that hard-lock systems when MSI is enabled,
including my own HVR-1250 when trying to use its built-in IR receiver.
Disable MSI and it works just fine. Similar for another user's HVR-1270.
Issues have also been reported with the HVR-1850 when MSI is enabled,
and the 1850 behavior sounds similar to an as-yet-undiagnosed issue I've
seen with an 1800.
