AKASHI Takahiro 6b0ddd1fbc virtio_blk: set log2blksz correctly
'log2blksz' in blk_desc structure must always be initialized, otherwise
it will cause a lot of weird failures in file operations.

For example, fs_set_blk_dev[_with_part]() examines a block device against
every file system with its probe function. In particular, ext4 file
system's ext4_probe() will calls fs_devread() to fetch a super block.
If log2blksz is 0, the actual 'read' size, i.e. block_len >> log2blksz, is
much bigger than a buffer's size, and it can end up with memory corruption.
