calipso: unlock rcu before returning -EAFNOSUPPORT
commit 3cae906e1a6184cdc9e4d260e4dbdf9a118d94ad upstream.
syzbot reported that a recent patch forgot to unlock rcu
in the error path.
Adopt the convention that netlbl_conn_setattr() is already using.
Fixes: 6e9f2df1c550 ("calipso: Don't call calipso functions for AF_INET sk.")
