DAOS-19116 object: do not log IO RPC DER_TIMEDOUT as ERROR - b28

DAOS client logic will resend IO request if hit DER_TIMEDOUT. That
is invisible to the application and not fatal. Logging it as ERROR
is confused and may fill the log file under some bad case, such as
server overloaded for very long time.
