[PATCH] Easy warning fix in ply-device-manager

[Alan Jenkins]

ply-device-manager.c: In function ‘create_devices_for_terminal_and_renderer_type’:
ply-device-manager.c:704:33: warning: ‘return’ with no value, in function returning non-void
                                 return;
                                 ^~~~~~

There's an earlier path "ignoring device %s since it's already managed"
which returns true.  This second early-return has the same message. I think
it also wants to return true.
