[PATCH 1/3] trace-cmd: Fix leaking of port_array memory

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

The port_array is allocated in create_all_readers() to send the ports that
are created to the client. But after it is sent, it is no longer needed, but
it was not freed. This causes a memory leak.
