mei: vsc: Destroy mutex after freeing the IRQ

The event_notify callback which runs from vsc_tp_thread_isr may call
vsc_tp_xfer() which locks the mutex. So the ISR depends on the mutex.

Move the mutex_destroy() call to after free_irq() to ensure that the ISR
is not running while the mutex is destroyed.
