Change kunmap macro to static inline function to fix build error
compiling drivers/base/dma-buf.c.
Without the change, the following error can occur:
CC drivers/base/dma-buf.o
/home/dave/debian/linux/linux-3.8.5/drivers/base/dma-buf.c: In
function 'dma_buf_kunmap':

I believe parisc is the only arch to implement kunmap using a macro.
