[PATCH v4 04/13] qemu: Use 'def->os.loader->nvram' directly instead of 'priv->pflash1'

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Since we now have a full virStorageSource for storing the nvram path we
don't need the extra dance of transfering the data into the 'pflash1'
variable which was an intermediary solution to use -blockdev.

For now we keep it functionally identical to the previous impl.
