[PATCH 1/9] mm/damon/core: remove unnecessary zero-initialization in damon_new_ctx()

[SJ Park]

From: "Adrian Huang (Lenovo)" <adrianhuang0701@xxxxxxxxx>

damon_new_ctx() allocates the context structure using kzalloc(),
which already initializes all fields to zero.

The explicit initialization of passed_sample_intervals,
next_aggregation_sis, and next_ops_update_sis is therefore redundant.
In addition, they are later initialized by kdamond_init_ctx() before use.

Remove the unnecessary assignments to simplify the code.
