mm/damon/lru_sort: use param_ctx for damon_attrs staging
damon_lru_sort_apply_parameters() allocates a new DAMON context, stages
user-specified DAMON parameters on it, and commits to running DAMON
context at once, using damon_commit_ctx(). The code is, however, directly
updating the monitoring attributes of the running context. And the
attributes are over-written by later damon_commit_ctx() call. This means
that the monitoring attributes parameters are not really working. Fix the
wrong use of the parameter context.
