When CL 533258 added frame pointer support for the block and mutex profiles, it deferred skipping/inline expansion, similar to the execution tracer. The first frame indicated whether this expansion was needed by holding either the number of frames to skip (implying inline expansion) or the logicalStackSentinel placeholder to indicate that no extra handling is needed. However, CL 598515 switched to doing the skipping/inline expansion at sample time. After this, the sentinel value is unused. This CL removes the sentinel from runtime lock profiling, correcting an oversight from that CL. This didn't cause any problems since post-processing would just ignore the bogus sentinel value; this is just a cleanup.
