GPU Crash from invalid SRV in CreateShaderResourceView due to integer underflow

The GPU crashes after the ray tracing geometry builder attempts to create a shader resource view with an invalid offset.

1. Open the sample project referenced from the Additional Info URL
2. Drag the BP_DiverSuit_InnerSuit Blueprint into the editor viewport
3. Drag a second BP_DiverSuit_InnerSuit Blueprint into the editor viewport

Expected
The Editor does not crash

Actual
The Editor issues a D3D validation error

D3D12 ERROR: ID3D12Device::CreateShaderResourceView: The Dimensions of the View are invalid due to at least one of the following conditions. Assuming this Format (0x27, R32_TYPELESS), FirstElement (value = 1844216) must be between 0 and the maximum offset of the Buffer, 1844215, inclusively. With the current FirstElement, NumElements (value = 1844214) must be between 1 and 0, inclusively, in order that the View fit on the Buffer. [ STATE_CREATION ERROR #31: CREATESHADERRESOURCEVIEW_INVALIDDIMENSIONS]D3D12: **BREAK** enabled for the previous message, which was: [ ERROR STATE_CREATION #31: CREATESHADERRESOURCEVIEW_INVALIDDIMENSIONS ]
