Subject: [PATCH] Cancel l2cap connection result future on abort

This cancels the `connection_result` future of LeCreditBasedChannel when
abort() is called, e.g. if the LE connection disconnects. This makes it
possible for code waiting for a connection to open to detect that the
connection has failed.

Fixes google/bumble#825
