mptcp: using TOKEN_MAX_RETRIES instead of magic number

Browse Source 
We have macro TOKEN_MAX_RETRIES for the number of token generate retries,
so using TOKEN_MAX_RETRIES in subflow_check_req().

And rename TOKEN_MAX_RETRIES to MPTCP_TOKEN_MAX_RETRIES as it is now
exposed.

Fixes: 535fb8152f ("mptcp: token: move retry to caller")
