ixgbevf: set the disable state when ixgbevf_qv_disable is called 

The ixgbevf_qv_disable function used by CONFIG_NET_RX_BUSY_POLL is broken,
because it does not properly set the IXGBEVF_QV_STATE_DISABLED bit, indicating
that the q_vector should be disabled (and preventing future locks from
obtaining the vector). This patch corrects the issue by setting the disable
state.
