HID: mcp2221: always initialize and cancel init_work

The writable gpio_mode_enforce parameter can change between probe and
remove.

If it changes from false to true after probe, remove skips cancellation
of init_work. Pending or running work can then access devm-managed
driver state after teardown. Changing it from true to false can make
remove cancel an uninitialized delayed work item.

Initialize init_work whenever IIO is reachable and cancel it
unconditionally on remove. Keep the parameter check only for scheduling
the initialization.

The false-to-true cancellation gap was previously reported by Sashiko.
We also encountered this issue during our static-analysis research.
