Remove IsValid Check on DHDD Data Input

[Denneisk]

Description:
When setting the DHDD Data input to an array using wires, the Memory output is changed accordingly. However, when using wirelinks to set Data, there appears to be no effect.

This PR allows wirelinks to properly set the Data input of DHDDs. The default behavior of DHDDs can still be expected as an input trigger with nil is already accounted for.

Issue

To Reproduce:

1. Create two DHDDs.

2. Create an E2 that outputs an array such as Out = array(...) and wire it to one DHDD.

3. Observe the memory of the DHDD with the debugger. It will contain all the data you pass to it.
   

4. Create another E2 that uses wirelinks such as DHDD["Data", array] = ... to set Data on the DHDD.

5. Observe the memory of the DHDD. It will contain nothing.
   

Expected behavior:
Setting Data through wirelink should update the DHDD appropriately.
