mm/damon/lru_sort: handle ctx allocation failure

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

mm/damon/lru_sort: handle ctx allocation failure

DAMON_LRU_SORT allocates the damon_ctx object for its kdamond in its init
function.  damon_lru_sort_enabled_store() wrongly assumes the allocation
will always succeed once tried.  If the damon_ctx allocation was failed,
therefore, code execution reaches to damon_commit_ctx() while 'ctx' is
NULL.  As a result, it dereferences the NULL 'ctx' pointer.  Avoid the
NULL dereference by returning -ENOMEM if 'ctx' is NULL.
