[PATCH net-next 1/7] mptcp: fix pr_debug in mptcp_token_new_connect

[Mat Martineau <mathew.j.martineau@linux.intel.com>]

From: Jianguo Wu <wujianguo@chinatelecom.cn>

After commit 2c5ebd001d4f ("mptcp: refactor token container"),
pr_debug() is called before mptcp_crypto_key_gen_sha() in
mptcp_token_new_connect(), so the output local_key, token and
idsn are 0, like:

  MPTCP: ssk=00000000f6b3c4a2, local_key=0, token=0, idsn=0

Move pr_debug() after mptcp_crypto_key_gen_sha().

Fixes: 2c5ebd001d4f ("mptcp: refactor token container")
