firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling
To parse the retrieved ID lists appropriately in
ffa_notification_info_get() the ids_processed variable should not
be pre-incremented - we are dropping an identifier at the
beginning of the list.
Fix it by using the post-increment operator to increment the number
of processed IDs.
