mm/damon/lru_sort: use param_ctx for damon_attrs staging

commit e18190b7e9 upstream.

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.
