[PATCH 4.14 197/211] usbip: tools: fix fd leakage in the function of read_attr_usbip_status

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Hewenliang <hewenliang4@xxxxxxxxxx>

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")
