ksmbd: smbd: fix missing client's memory region invalidation
mainline inclusion from mainline-5.17-rc1 commit 2fd5dcb1 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G CVE: NA Reference: https://git.kernel.org/torvalds/linux/c/2fd5dcb1c8ef ------------------------------- if the Channel of a SMB2 WRITE request is SMB2_CHANNEL_RDMA_V1_INVALIDTE, a client does not invalidate its memory regions but ksmbd must do it by sending a SMB2 WRITE response with IB_WR_SEND_WITH_INV. But if errors occur while processing a SMB2 READ/WRITE request, ksmbd sends a response with IB_WR_SEND. So a client could use memory regions already in use.
