Subject: rtc: rtc-hid-sensor-time: fix possible bug on driver_remove
The work we schedule on register deletes himself. Therefor we cannot
use cancel_work_sync() because that calls flush_work() but still uses
the pointer to the (now deleted) work afterwards (for clear_work_data)
which ends up in a bug.
Replacing cancel_work_sync() with flush_work() fixes that.
