gpio: aggregator: cancel deferred probe for devices created via configfs
For aggregators initialized via configfs, write 1 to 'live' waits for
probe completion and returns an error if the probe fails, unlike the
legacy sysfs interface, which is asynchronous.
Since users control the liveness of the aggregator device and might be
editing configurations while 'live' is 0, deferred probing is both
unnatural and unsafe.
Cancel deferred probe for purely configfs-based aggregators when probe
fails.
