[logger_olp] Avoid repeated calls to persistent_term:put
logger_otp would call back to persistent_term:put on each iteration even when the mode wouldn't actually change. Even though persistent_term:put guards against changing value to the same avoiding the most expensive operations, it still aquires some locks and does potentially other fairly expensive work. We can avoid this with a simple check in logger_olp to try and update the value only if it has actually changed.
