media: i2c: adv7842: Remove redundant cancel_delayed_work in probe

The delayed_work delayed_work_enable_hotplug is initialized with
INIT_DELAYED_WORK() in adv7842_probe(), but it is never scheduled
anywhere in the probe function.

Calling cancel_delayed_work() on a work that has never been
scheduled is redundant and unnecessary, as there is no pending
work to cancel.

Remove the redundant cancel_delayed_work() from error handling
path and adjust the goto label accordingly to simplify the code
and avoid potential confusion.
