mptcp: remove thmac from subflow ctx

Browse source

This entry is only used in subflow_finish_connect().

Instead, use the original value from mp_opt, and pass it to
subflow_thmac_valid() to do the validation with the given truncated
hmac.

While at it, rename the variables in subflow_thmac_valid() to avoid
confusions about the received one vs the expected one.
