Also make the fallback decision as early as possible.

The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

The same problem was reported for 2230S, in which case it wasn't actually clear whether the culprit is the controller or the mainboard, though. In order to be on the safe side, flag MSIs as being broken with the latter type of controller as well. Given that these are the only reports of MSI-related breakage with aac(4) so far and OSes like OpenSolaris unconditionally employ MSIs for all adapters of this family, however, it doesn't seem warranted to generally disable the use of MSIs in aac(4). While at it, simplify the MSI allocation logic a bit; there's no need to check for the presence of the MSI capability on our own as pci_alloc_msi(9) will just fail when these kind of interrupts are not available.
