The block descriptor contains the if_type. There is no need to first look up the uclass for the if_type and then to check the parent device's uclass to know if the device has the correct if_type.

This seems to be heading in the wrong direction though.
The IF_TYPE should really go away and be replaced with the UCLASS ID, I think.
At present we have lots of calls to blk_create_device_f() which specify the type. I think we should drop the IF_TYPE_.. arg to that function and have it figured out from the uclass, in the interim.
But why do we need IF_TYPE now?
