Subject: [PATCH 5.4 54/66] usbip: tools: fix fd leakage in the function of read_attr_usbip_status

From: Hewenliang <hewenliang4@...wei.com>

commit 26a4d4c00f85cb844dd11dd35e848b079c2f5e8f upstream.

We should close the fd before the return of read_attr_usbip_status.

Fixes: 3391ba0e2792 ("usbip: tools: Extract generic code to be shared with vudc backend")
