net: tcp_lp: fix kernel-doc warnings and update outdated reference links

Fix kernel-doc warnings in tcp_lp.c by adding missing parameter
descriptions for tcp_lp_cong_avoid() and tcp_lp_pkts_acked() when
building with W=1.

Also replace invalid URLs in the file header comment with the currently
valid links to the TCP-LP paper and implementation page.

No functional changes.
