[PATCH 10/18] rcu: rcupdate.h: get rid of Sphinx warnings at rcu_pointer_handoff()

[Mauro Carvalho Chehab]

The code example at rcupdate.h currently produce lots of warnings:

	./include/linux/rcupdate.h:572: WARNING: Unexpected indentation.
	./include/linux/rcupdate.h:576: WARNING: Unexpected indentation.
	./include/linux/rcupdate.h:580: WARNING: Block quote ends without a blank line; unexpected unindent.
	./include/linux/rcupdate.h:582: WARNING: Block quote ends without a blank line; unexpected unindent.
	./include/linux/rcupdate.h:582: WARNING: Inline literal start-string without end-string.

Change it to a code-block.
