usbip: Fix infinite loop in vhci rx

https://lore.kernel.org/linux-usb/20191206032406.GE1208@mail-itl/T/#u
In this mail thread, it shows system hang when there is receive
error in vhci. There are two different causes in this bug.

[1] Wrong receive logic in vhci when using scatter-gather
[2] Wrong error path of vhci_recv_ret_submit()

[1] considers normal reception to be an error condition and closes
connection. And when [1] error situation occurs, wrong error path[2]
causes the system freeze. So each patch fixes this bugs.
