optee: fix uninited async notif value



Fixes an uninitialized variable in irq_handler() that could lead to
unpredictable behavior in case OP-TEE fails to handle SMC function ID
OPTEE_SMC_GET_ASYNC_NOTIF_VALUE. This change ensures that in that case
get_async_notif_value() properly reports there are no notification
event.
