[PATCH v2 0/1] MR9247: server: avoid crash on deleted registry subkeys in find_subkey

[zhengyong chen (＠chenzhengyong)]

find_subkey() can crash when accessing a deleted subkey. When a key
is deleted, its node may remain in the subkeys array but key->obj.name
becomes NULL due to unlink_named_object(). This can happen when iterating
over subkeys during rename or delete operations.
