Steven Rostedt a8632ef4fc tracing/osnoise: Fix build when timerlat is not enabled 
commit af178143343028fdec9d5960a22d17f5587fd3f5 upstream.

To fix some critical section races, the interface_lock was added to a few
locations. One of those locations was above where the interface_lock was
declared, so the declaration was moved up before that usage.
Unfortunately, where it was placed was inside a CONFIG_TIMERLAT_TRACER
ifdef block. As the interface_lock is used outside that config, this broke
the build when CONFIG_OSNOISE_TRACER was enabled but
CONFIG_TIMERLAT_TRACER was not.
