Summary
mm/damon/reclaim: fix potential memory leak in damon_reclaim_init()
Details

In the Linux kernel, the following vulnerability has been resolved:

mm/damon/reclaim: fix potential memory leak in damonreclaiminit()

damonreclaiminit() allocates a memory chunk for ctx with damonnewctx(). When damonselectops() fails, ctx is not released, which will lead to a memory leak.

We should release the ctx with damondestroyctx() when damonselectops() fails to fix the memory leak.
