  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.
