mtd: rawnand: nandsim: Fix the logic when selecting Hamming soft ECC engine
I have been fooled by the logic picking the right ECC engine which is
spread across two functions: *init_module() and *_attach(). I thought
this driver was not impacted by the recent changes around the ECC
engines DT parsing logic but in fact it is.
