rt2x00: Remove Q_INDEX_CRYPTO and ENTRY_OWNER_DEVICE_CRYPTO

Q_INDEX_CRYPTO and ENTRY_OWNER_DEVICE_CRYPTO where initially
added with the plan to implement hardware encryption for rt2500pci.
However there are no plans to do so anymore as the crypto
mechanism in rt2500pci is very different then any other Ralink
device.

So we can now safely remove the definitions, and don't think
about this feature anymore. :)
