mm/z3fold: add kerneldoc fields for z3fold_pool
make W=1 generates the following warning for z3fold_pool
mm/z3fold.c:171: warning: Function parameter or member 'zpool' not described in 'z3fold_pool'
mm/z3fold.c:171: warning: Function parameter or member 'zpool_ops' not described in 'z3fold_pool'
Commit 9a001fc19ccc ("z3fold: the 3-fold allocator for compressed pages")
simply did not document the fields at the time. Add rudimentary
documentation.
