net/core: move the lockdep-init of sk_callback_lock to sk_init_common()
In commit cdfbabfb2f0c ("net: Work around lockdep limitation in sockets that use sockets"), it introduces 'af_kern_callback_keys' to lockdep-init of sk_callback_lock according to 'sk_kern_sock', it modifies sock_init_data() only, and sk_clone_lock() calls sk_init_common() to initialize sk_callback_lock too, so the lockdep-init of sk_callback_lock should be moved to sk_init_common().
