Subject: [PATCH] USB: usbip: remove useless call in usbip_recv
Git-commit: 55448d85ae2f7f2b6c43d66946146ec89b4eb088
Patch-mainline: v4.16-rc1
References: bsc#1087092
Calling msg_data_left(&msg) is only useful for its return value,
which in this particular case is ignored.
Fix this by removing such call.
