rcu_sync: Cleanup the CONFIG_PROVE_RCU checks
1. Rename __rcu_sync_is_idle() to rcu_sync_lockdep_assert() and change it to use rcu_lockdep_assert(). 2. Change rcu_sync_is_idle() to return rsp->gp_state == GP_IDLE unconditonally, this way we can remove the same check from rcu_sync_lockdep_assert() and clearly isolate the debugging code. Note: rcu_sync_enter()->wait_event(gp_state == GP_PASSED) needs another CONFIG_PROVE_RCU check, the same as is done in ->sync(); but this needs some simple preparations in the core RCU code to avoid the code duplication.
