spa_preferred_class: pass the entire zio

Browse Source 
Rather than picking out specific values out of the properties, just pass
the entire zio in, to make it easier in the future to use more of that
info to decide on the storage class.

I would have rathered just pass io_prop in, but having spa.h include
zio.h gets a bit tricky.
