srcu: Remove superfluous ssp initialization for early callbacks
Pre-srcu_init() invocations of call_srcu() initialize the srcu_struct structure in question, so there is no need to check this initialization in srcu_init() when initiating grace periods for srcu_struct structures that had early call_srcu() invocations. This commit therefore drops the calls to check_init_srcu_struct() in srcu_init().
