tests/qtest/libqos/e1000e: Set E1000_CTRL_SLU

The later device status check depends on E1000_STATUS_LU, which is
enabled by E1000_CTRL_SLU. Though E1000_STATUS_LU is not implemented
and E1000_STATUS_LU is always available in the current implementation,
be a bit nicer and set E1000_CTRL_SLU just in case the bit is
implemented in the future.
