rcutorture: Exercise DEFINE_STATIC_SRCU_FAST() and init_srcu_struct_fast()

Browse Source 
This commit updates the initialization for the "srcu" and "srcud" torture
types to use DEFINE_STATIC_SRCU_FAST() and init_srcu_struct_fast(),
respectively, when reader_flavor is equal to SRCU_READ_FLAVOR_FAST.
