It seems you always try to intialize OPAL even if the drive doesn't support it.
I think you should check if the device supports security commands and then see
if it supports OPAL before calling this. See e.g.
https://lkml.org/lkml/2016/6/19/139 . Ideally, this code would check all
supported protocols and initialize the appropriate security device based on that.
