f8ea0b00e087380fa0c7309f843f67b7e2d0126a block: Make find_image_format() return 'raw' BlockDriver for SG_IO devices
This patch adds a special BlockDriverState->sg check in block.c:find_image_format()
after bdrv_file_open() -> block/raw-posix.c:hdev_open() has been called to determine
if we are dealing with a Linux host scsi-generic device.
The patch then returns the BlockDriver * from bdrv_find_format("raw"), skipping the
subsequent bdrv_read() and rest of find_image_format().
