tracing: remove recursive test from ring_buffer_event_discard
The ring_buffer_event_discard is not tied to ring_buffer_lock_reserve.
It can be called inside or outside the reserve/commit. Even if it
is called inside the reserve/commit the commit part must also be called.
Only ring_buffer_discard_commit can be used as a replacement for
ring_buffer_unlock_commit.
This patch removes the trace_recursive_unlock from ring_buffer_event_discard
since it would be the wrong place to do so.
[Impact: prevent breakage in trace recursive testing ]
