rcu: Get rid of some doc warnings in update.c

This commit escapes *ret, because otherwise the documentation system
thinks that this is an incomplete emphasis block:

	./kernel/rcu/update.c:65: WARNING: Inline emphasis start-string without end-string.
	./kernel/rcu/update.c:65: WARNING: Inline emphasis start-string without end-string.
	./kernel/rcu/update.c:70: WARNING: Inline emphasis start-string without end-string.
	./kernel/rcu/update.c:82: WARNING: Inline emphasis start-string without end-string.
