net: usb: rtl8150: handle link status read failures
set_carrier() ignores the result of the USB control transfer and tests
the stack variable supplied as its receive buffer. If the device rejects
or aborts the request, that variable remains uninitialized and the driver
chooses an arbitrary carrier state.
Leave the existing carrier state unchanged when the link status cannot be
read. A transient USB error should not be treated as link loss.
