The threads for listening on the telemetry sockets are control threads
and should be separated from those on the data plane. Since telemetry
cannot use the rte_ctrl_thread_create() API, as it does not depend on
EAL, we pass the ctrl thread cpu_set to telemetry init and use it
directly to ensure that telemetry cannot interfere with the data plane
threads.

The strchr function return was not being checked which could lead to
NULL deferencing later in the function.

The return value from the socket function is now checked, as it can
return a negative value on error.

If 1024 bytes were received over the socket, this caused
buffer_recvf[bytes] to overrun the array. The size of the buffer - 1 is
now passed to the read function.
