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().
