[SCSI] aacraid: remove duplicate io callback code

Browse source 
Received from Mark Salyzyn from Adaptec:

This patch removes the duplicate code in the write_callback command
completion handler, and renames read_callback to io_callback. Optimized
the lba calculation into the debug print routine macro to optimize the
i/o code path.
