ixgbe: fix disable interrupt twice

Currently, ixgbe vf and pf will disable interrupt twice in
stop stage and uninit stage. It will cause an error:

    testpmd> quit

    Shutting down port 0...
    Stopping ports...
    Done
    Closing ports...
    EAL: Error disabling MSI-X interrupts for fd 26
    Done

because the interrupt has already been disabled in stop stage.
Since it is enabled in init stage, better remove from
stop stage.

Fixes: 0eb609239efd ("ixgbe: enable Rx queue interrupts for PF and VF")
