block: saner flags filtering in bdrv_open2
Clean up the current mess about figuring out which flags to pass to the driver. BDRV_O_FILE, BDRV_O_SNAPSHOT and BDRV_O_NO_BACKING are flags only used by the block layer internally so filter them out directly. Previously BDRV_O_NO_BACKING could accidentally be passed to the drivers, but wasn't ever used. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
