cpufreq: intel_pstate: cancel HWP notify work in driver cleanup
intel_pstate_driver_cleanup() frees per-CPU data without cancelling the
pending HWP notify delayed work. If hwp_notify_work is still scheduled
or running when the struct is freed, the work function accesses freed
memory via container_of().
Call intel_pstate_disable_hwp_interrupt() before kfree() to disable
the interrupt source and cancel the pending work, matching the pattern
used in intel_pstate_suspend() and intel_pstate_hwp_offline().
