SVN rev 221138 on 2011-04-27 20:08:44Z by jhb
Only align MSI message groups based on the number of messages being
allocated, not the maximum number of messages the device supports. The
spec only requires the former, and I believe I implemented the latter due
to misunderstanding an e-mail. In particular, this fixes an issue where
having several devices that all support 16 messages can run out of
IDT vectors on x86 even though the driver only uses a single message.
