Fix erroneous logic for handling step and block size in prior commit

The earlier change had a logical misconception. If PluginStub is
receiving the correct step and block size back from the configure call,
the plugin on the server side must have already been successfully
initialised, as the step and block size are only returned in a
successful configure response. This means the test for a failed
initialise and redo with the correct parameters must be done on the
server side (in LoaderRequests) not the client. The client has a more
complicated job, which is to notice that a *successful* configure had
returned different framing parameters from those passed to the
initialise call, and to pretend that it had actually failed until the
host called again with the correct parameters. We definitely need tests
for this!
