!= was used in place of <, while comparing expected and actual payload
size. The module may be running a higher version of the protocol and
might have some extra fields (towards the end) in the structure, and the
AP needs to ignore them.

This also updates the print (expected-payload-size <
actual-payload-size), when the size doesn't match for requests received
by the module. This gives more details required for debugging.

The error paths in gb_loopback_connection_init() are kind of screwed
up--not in proper order, and the label naming convention seems a
little inconsistent.

Fix this, ensuring each error cleans up the setup that's been done
up to that point.  Use the convention that the label indicates the
first thing that needs to be cleaned up.

Reorder the statements in gb_loopback_connection_exit() to match
the order of cleanup in gb_loopback_connection_init().
