rcu: Fix macro substitution for synchronize_rcu_bh() on RT
kernel/rcutorture.c:492: error: ‘synchronize_rcu_bh’ undeclared here (not in a function)
synchronize_rcu_bh() is not just called as a normal function, but can
also be referenced as a function pointer. When CONFIG_PREEMPT_RT_FULL
is enabled, synchronize_rcu_bh() is defined as synchronize_rcu(), but
needs to be defined without the parenthesis because the compiler will
complain when synchronize_rcu_bh is referenced as a function pointer
and not a function.
