CF_CFDP_DisableEngine no longer disables the engine

[jphickey]

Describe the bug
The line which actually disables the engine got mistakenly deleted in a recent PR. (Got swept up because it was grouped with the variable declarations with no whitespace between).

To Reproduce
Issue disable engine command, it does not actually disable

Expected behavior
Should disable the engine
