cciss: use upper_32_bits() macro to eliminate warnings

Browse source 
Use upper_32_bits(x) macro to handle shifts that may be >= the width of
the data type.

drivers/block/cciss.c: In function 'do_cciss_request':
drivers/block/cciss.c:2655: warning: right shift count >= width of type
drivers/block/cciss.c:2656: warning: right shift count >= width of type
drivers/block/cciss.c:2657: warning: right shift count >= width of type
drivers/block/cciss.c:2658: warning: right shift count >= width of type
