bootstd: Probe the block device before use

Browse Source 
In some cases the block device is obtained but is not probed, since it
is a sibling of the bootdev. Make sure it is probed, so it can be used
without any trouble.

This fixes a bug with virtio, where the device is accessed before it has
been set up by the virtio uclass.
