rcu: Remove unused rdp parameter from trace_rcu_this_gp()

Browse source

The trace_rcu_this_gp() wrapper forwards only the rcu_node structure's
fields and the requested grace-period sequence number to the
rcu_future_grace_period tracepoint.  Its rcu_data pointer parameter
has no users, but every one of the ten call sites must nevertheless
come up with an rcu_data pointer to pass in.

Remove the parameter and update all callers.  This also allows
rcu_future_gp_cleanup() to drop the local rcu_data pointer that
existed solely to feed this trace call.

No functional change.
