lib/ovs-rcu: Support static initialization.

Currently, OVSRCU_TYPE_INITIALIZER always initializes the RCU pointer
as NULL.  There is no reason why the RCU pointer could not be
initialized with a non-NULL value, however, as statically allocated
memory is even more stable than required for RCU.

This patch changes the initializer to OVSRCU_INITIALIZER(VALUE), which
can take any pointer value as a parameter.

This allows rculist, which is introduced in a following patch, to
provide an initializer similar to the one in the normal list.
