[PATCH] MegaRAID - compile fix for 2.5.9

  This fixes compile errors.  It has been tested with a weekend of Bonnie++ 8GB
runs on a RAID0 setup at the OSDL.  This was built against and tested on 2.5.8
and applies cleanly to 2.5.9.

  LSI told me they have a version 2.0 of the driver in development but
it would be really nice to have the dang thing working now ;-)
