dma-buf: Add syntax highlighting to code listings in the document

Browse source 
This patch tries to improve the display of the code listing
on The Linux Kernel documentation website for dma-buf [1] .

Originally, it appears that it was attempting to escape
the '*' character, but looks like it's not necessary (now),
so we are seeing something like '\*' on the webite.

This patch removes these unnecessary backslashes and adds syntax
highlighting to improve the readability of the code listing.
