[PATCH] mm/damon/core: nullify pointer ctx->kdamond with a NULL

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently a plain integer is being used to nullify the
pointer ctx->kdamond. Use NULL instead. Cleans up sparse
warning:

mm/damon/core.c:317:40: warning: Using plain integer as NULL pointer
