dapl: fix ring buffer synchronization

The dapl ring buffer implementation is not thread safe.  Replace
the use of atomic variables with actual locking to ensure that
there are not races inserting and/or removing items at the same time.

Without proper synchronization, the EVD can report invalid events or
the same event multiple times.
