xfs: fortify xfs_alloc_buftarg error handling
percpu_counter_init failure path doesn't clean up &btp->bt_lru list.
Call list_lru_destroy in that error path. Similarly register_shrinker
error path is not handled.
While it is unlikely to trigger these error path, it is not impossible
especially the later might fail with large NUMAs. Let's handle the
failure to make the code more robust.
