Subject: mm/damon/reclaim: use damon_kdamond_pid()

DAMON_RECLAIM directly uses damon_ctx->kdamond field with manual synchronization using damon_ctx->kdamond_lock, to get the pid of the kdamond. Use a new dedicated function for the purpose, namely damon_kdamond_pid(), since that doesn't require manual and error-prone synchronization.
