[SELinux]: Fix double free in selinux_netlbl_sock_setsid()
As pointed out by Adrian Bunk, commit
45c950e0f839fded922ebc0bfd59b1081cc71b70 ("fix memory leak in netlabel
code") caused a double-free when security_netlbl_sid_to_secattr()
fails. This patch fixes this by removing the netlbl_secattr_destroy()
call from that function since we are already releasing the secattr
memory in selinux_netlbl_sock_setsid().
