kho: always expose output FDT in debugfs

Browse Source 
Currently, the output FDT is added to debugfs only when KHO is finalized
and removed when aborted.

There is no need to hide the FDT based on the state.  Always expose it
starting from initialization.  This aids the transition toward removing
the explicit abort functionality and converting KHO to be fully stateless.
