[PATCH] firmware: arm_ffa: fix ffa_notification_info_get()

[Jens Wiklander]

FFA_NOTIFICATION_INFO_GET retries information about pending
notifications. Notifications can be either global or per VCPU. Global
notifications are represented by the VM ID only, or 0 in the absence of
a hypervisor. ffa_notification_info_get() incorrectly expect no ID at all
for global notifications. Fix this by checking for 1 ID instead of 0.
