From: Longfang Liu <liulongfang@huawei.com> In the No-SVA mode of UADK, a feature was implemented to reserve memory allocated for shared queues, which was exposed to external users through the wd_share_reserved_memory interface. After this functionality was removed from the kernel-space UACCE, the corresponding external interface in UADK must also be deleted to maintain consistency.
