net: lib: coap: Add error check when waking server thread

rlubos · henrikbrixandersen · commit bc2858ad2d5a · 2024-02-19T19:07:03.000+01:00
There's not much to be done in case waking up the server thread with
socketpair send() fails, but at least we can log an error on such event
(to please coverity).
