block: Remove blk_attach_dev_legacy() / legacy_dev code

Browse source 
The last user of blk_attach_dev_legacy() was the code in xen_disk which
has recently been reworked. Now there is no user for this legacy function
anymore. Thus we can finally remove all code related to the "legacy_dev"
flag, too, and turn the related "void *" in block-backend.c into proper
"DeviceState *" to fix some of the remaining TODOs there.
