Documentation/spi/* compile warning fix 

Fix this warning:

Documentation/spi/spidev_fdx.c: In function `do_msg':
Documentation/spi/spidev_fdx.c:61: warning: cast from pointer to integer of different size
Documentation/spi/spidev_fdx.c:64: warning: cast from pointer to integer of different size

buf should be unsigned long to match native arch on 32-bit x86 compile.
