mm/damon/reclaim: use parameter context correctly

Browse source

damon_reclaim_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 mistakenly
over-writing the monitoring attributes and the reclaim scheme on the
running context.  It is not causing a real problem for monitoring
attributes, but the scheme overwriting can remove scheme's internal status
such as charged quota.  Fix the wrong use of the parameter context.
