net: fix sock_timestamping_bind_phc() to release device
commit 2a4d75bfe41232608f5596a6d1369f92ccb20817 upstream.
Don't forget to release the device in sock_timestamping_bind_phc() after
it was used to get the vclock indices.
Fixes: d463126e23f1 ("net: sock: extend SO_TIMESTAMPING for PHC binding")
