Jianglei Nie 700aa4e11a mm/damon/reclaim: fix potential memory leak in damon_reclaim_init() 
[ Upstream commit 188043c7f4 ]

damon_reclaim_init() allocates a memory chunk for ctx with
damon_new_ctx().  When damon_select_ops() fails, ctx is not released,
which will lead to a memory leak.

We should release the ctx with damon_destroy_ctx() when damon_select_ops()
fails to fix the memory leak.
