Remove high frequency log to avoid the log full with useless information

Remove high frequency log to avoid the log full with useless information

The OCProcess function is invoked in while loop. The functions that are
invoked by OCProcess will be invoked very frequently. If add log in these
functions, it may make the log full of useless information.

This patch removes frequent log from OCProcess/OCProcessPresence/
OCProcessCoAP/coap_read/OCRecvFrom function.
