dcsctp: Apply chunk before apply deferred reset

When a RECONFIG has been received with a last assigned TSN that is
not yet seen by the receiver, it will enter deferred reset mode
(https://www.rfc-editor.org/rfc/rfc6525#section-5.2.2, E2).

When more DATA is received, moving the cumulative acknowledgment point,
the request will finally be processed. But the last chunk that has the
same TSN as the last assigned TSN was before this CL not applied before
doing the reset - it was applied after.

This would result of a message getting lost or possibly getting
truncated or incorrectly merged with another.

Handling the message before resetting the stream is the simple
solution here.
