If instantiation of a card failed, we have to remove it from the card list. This fixes an Oops on Migo-R, triggering, when after a failed firmware load attempt the driver modules are removed and re-inserted again.
This looks like the wrong fix - if the card failed to instantiate because the component drivers weren't ready then it ought to hang around so it can be instantiated once they appear. Presumably some part of the instantiation attempt is failing and not being unwound properly?

Should also be good for stable.
