ipfix-export: Fix frame leak in flow_report_process_send()
The flow_report_process_send() function always allocates a frame.
However, when no template_send is needed, template_bi is ~0.
When this happens, no vectors are placed in the frame. When
the frame is then "put", a check for n_vectors == 0 prevents
the frame from actually being placed back on the free list.
Fix that by using a direct call to vlib_frame_free() when
there are no frame vctors.
Type: fix
