spi: mpc52xx: Add cancel_work_sync before module remove

If we remove the module which will call mpc52xx_spi_remove it will free 'ms' through spi_unregister_controller. while the work ms->work will be used. The sequence of operations that may lead to a UAF bug.

Fix it by ensuring that the work is canceled before proceeding with the cleanup in mpc52xx_spi_remove.
