hw/nvme: reimplement format nvm to allow cancellation

Browse source 
Prior to this patch, the aios associated with broadcast format are
submitted anonymously (no aiocb reference saved from the blk_aio call).

Fix this by formatting the namespaces one after another, saving a
reference to the aiocb for each.
