extcon: max14577: Fix probe failure on successful work queue

Browse Source 
commit 12adef5b49 upstream.

In probe the driver queued delayed work for cable detection and
returned the result of queue_delayed_work() call. However the return
value of queue_delayed_work() does not indicate an error and in normal
condition it returns true which means successful work queue.
This effectively resulted in probe failure:
[    2.088204] max14577-muic: probe of max77836-muic failed with error 1
