wifi: iwlwifi: mld: fix race condition in PTP removal
iwl_mld_ptp_remove() calls cancel_delayed_work_sync() only after
ptp_clock_unregister() and clearing ptp_data state (ptp_clock,
last_gp2, wrap_counter).
This creates a race where the delayed work iwl_mld_ptp_work() can
execute between ptp_clock_unregister() and cancel_delayed_work_sync(),
observing partially cleared PTP state.
Move cancel_delayed_work_sync() before ptp_clock_unregister() to
ensure the delayed work is fully stopped before any PTP cleanup
begins.
