usb: typec: tipd: Prevent uninitialized event{1,2} in IRQ handler
If reading TPS_REG_INT_EVENT1/2 fails in the interrupt handler event1
and event2 may be uninitialized when they are used to determine
IRQ_HANDLED vs. IRQ_NONE in the error path.
Fixes: c7260e29dd20 ("usb: typec: tipd: Add short-circuit for no irqs")
Fixes: 45188f27b3d0 ("usb: typec: tipd: Add support for Apple CD321X")
