[PATCH v4 24/52] docs: it_IT: fix namespace collisions at locking.rst

[Mauro Carvalho Chehab]

The C domain functions there collide with the English ones,
due to namespace collision, generating lots of warnings with
Sphinx 3.x:

	./include/linux/mutex.h:121: WARNING: Duplicate C declaration, also defined in 'translations/it_IT/kernel-hacking/locking'.
	Declaration is 'mutex_init'.
	./include/linux/mutex.h:152: WARNING: Duplicate C declaration, also defined in 'translations/it_IT/kernel-hacking/locking'.
	Declaration is 'mutex_is_locked'.
	./include/linux/mutex.h:226: WARNING: Duplicate C declaration, also defined in 'translations/it_IT/kernel-hacking/locking'.
	Declaration is 'mutex_trylock_recursive'.
	./kernel/locking/mutex.c:281: WARNING: Duplicate C declaration, also defined in 'translations/it_IT/kernel-hacking/locking'.
	Declaration is 'mutex_lock'.
	...

Add a namespace tag there, in order to prevent that.
