doc: remove reference to pcapng init function

  The rte_pcapng_init function doesn't exist, so remove it from the docs.

Also fix minor mistakes in the file.

The rte_pcapng_init function existed in earlier versions of patches for
this file on the mailing list, but was dropped in favour of
RTE_INIT(pcapng_init) which doesn't need to be called explicitly by the
programmer, if I understand the RTE_INIT macro correctly.

Yes, this is leftover from earlier code.

Applied, thanks.
