    rcuperf: Fix perf_type module-parameter description
    
    The rcu_bh rcuperf type was removed by commit 620d246065cd("rcuperf:
    Remove the "rcu_bh" and "sched" torture types"), but it lives on in the
    MODULE_PARM_DESC() of perf_type.  This commit therefore changes that
    module-parameter description to substitute srcu for rcu_bh.
