[PATCH] genalloc: Fix a set of docs build warnings

[PATCH] genalloc: Fix a set of docs build warnings

[Jonathan Corbet]

Commit 795ee30648c7 ("lib/genalloc: introduce chunk owners") made a number
of changes to the genalloc API and implementation but did not update the
documentation to match, leading to these docs build warnings:

  ./lib/genalloc.c:1: warning: 'gen_pool_add_virt' not found
  ./lib/genalloc.c:1: warning: 'gen_pool_alloc' not found
  ./lib/genalloc.c:1: warning: 'gen_pool_free' not found
  ./lib/genalloc.c:1: warning: 'gen_pool_alloc_algo' not found

Fix these by updating the docs to match new function locations and names,
and by completing the update of one kerneldoc comment.

Thanks Jon. Apologies for the lack of due diligence on my part.
Changes look good to me.
