Peter Krempa 6eaf3614b6 qemuBlockStorageSourceNeedsFormatLayer: Stop formatting 'raw' driver when not needed 
The 'raw' driver without any special configuration is not needed and
creates overhead in qemu.

Stop using the 'raw' format driver in cases when it's not needed. A
special case when it is needed is for FD passed images with only a
single writable FD passed, where we need an overlay driver to properly
reflect the 'read-only' flag.
