[ros-diffs] [cgutman] 48212: [NDIS] - Verify that each adapter has been initialized before passing it to the protocol's BindAdapter function - Also verify that each adapter has not already been bound to the protocol - Miniport drivers can now function without a reboot (needed to use 3rd-party NIC drivers on the live CD)

[NDIS]
- Verify that each adapter has been initialized before passing it to the protocol's BindAdapter function
- Also verify that each adapter has not already been bound to the protocol
- Miniport drivers can now function without a reboot (needed to use 3rd-party NIC drivers on the live CD)
