Etienne Carriere 06ec5be891 optee: fix uninited async notif value

commit 654d0310007146fae87b0c1a68f81e53ad519b14 upstream.

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.
