    net: txgbe: initialize num_q_vectors for MSI/INTx interrupts
    
    [ Upstream commit 7c36711a2cd8059c2d24f5e5c1d76e8ea2d5613c ]
    
    When using MSI/INTx interrupts, wx->num_q_vectors is uninitialized.
    Thus there will be kernel panic in wx_alloc_q_vectors() to allocate
    queue vectors.
