[PATCH] I2O: first code cleanup of spare warnings and unused functions

Changes:

 - Removed unnecessary checking of NULL before calling kfree()
 - Make some functions static
 - Changed pr_debug() into osm_debug()
 - Use i2o_msg_in_to_virt() for getting a pointer to the message frame
 - Cleaned up some comments
 - Changed some le32_to_cpu() into readl() where necessary
 - Make error messages of OSM's look the same
 - Cleaned up error handling in i2o_block_end_request()
 - Removed unused error handling of failed messages in Block-OSM, which
   are not allowed by the I2O spec
 - Corrected the blocksize detection in i2o_block
 - Added hrt and lct sysfs-attribute to controller
 - Call done() function in SCSI-OSM after freeing DMA buffers
 - Removed unneeded variable for message size calculation in
   i2o_scsi_queuecommand()
 - Make some changes to remove sparse warnings
 - Reordered some functions
 - Cleaned up controller initialization
 - Replaced some magic numbers by defines
 - Removed unnecessary dma_sync_single_for_cpu() call on coherent DMA
 - Removed some unused fields in i2o_controller and removed some unused
   functions
