circpad_setup_machine_on_circ(): exit early on error.
This function does a nonfatal assertion to make sure that a machine
is not registered twice, but Tobias Pulls found a case where it
happens. Instead, make the function exit early so that it doesn't
cause a remotely triggered memory leak.
Fixes bug 33619; bugfix on 0.4.0.1-alpha. This is also tracked as
TROVE-2020-004.
