apparmor: fix incorrect type assignment when freeing proxies
sparse reports poisoning the proxy->label before freeing the struct is resulting in a sparse build warning. ../security/apparmor/label.c:52:30: warning: incorrect type in assignment (different address spaces) ../security/apparmor/label.c:52:30: expected struct aa_label [noderef] <asn:4>*label ../security/apparmor/label.c:52:30: got struct aa_label *<noident> fix with RCU_INIT_POINTER as this is one of those cases where rcu_assign_pointer() is not needed.
