Also, describe more details of bind().

a/an usage.  Thanks @KenanSulayman

`maybeInitFinished()` can emit the 'secure' event which
in turn destroys the connection in case of authentication
failure and sets `this.pair.ssl` to `null`.

If such condition appeared after non-empty read - loop will continue
and `clearOut` will be called on `null` object instead of
`crypto::Connection` instance. Resulting in the following assertion:

    ERROR: Error: Hostname/IP doesn't match certificate's altnames
    Assertion failed: handle->InternalFieldCount() > 0

fix #5756
