Subject: [for-next][PATCH 3/6] tracing: Remove __idx variable from __DO_TRACE

From: Mathieu Desnoyers <mathieu.desnoyers@...icios.com>

Since the removal of SRCU-protected tracepoints, the __idx variable in
__DO_TRACE is unused. Remove this variable.

Fixes: 48bcda684823 ("tracing: Remove definition of trace_*_rcuidle()")
