Subject: [PATCH 09/14] mm/zbud: Add kerneldoc fields for zbud_pool

make W=1 generates the following warning for zbud_pool

  mm/zbud.c:105: warning: Function parameter or member 'zpool' not described in 'zbud_pool'
  mm/zbud.c:105: warning: Function parameter or member 'zpool_ops' not described in 'zbud_pool'

Commit 479305fd7172 ("zpool: remove zpool_evict()") removed the zpool_evict
helper and added the associated zpool and operations structure in struct
zbud_pool but did not add documentation for the fields. Add rudimentary
documentation.

Fixes: 479305fd7172 ("zpool: remove zpool_evict()")
