block: Always set writeback mode in blk_new_open()
All callers of blk_new_open() either don't rely on the WCE bit set after blk_new_open() because they explicitly set it anyway, or they pass BDRV_O_CACHE_WB unconditionally. This patch changes blk_new_open() so that it always enables writeback mode and asserts that BDRV_O_CACHE_WB is clear. For those callers that used to pass BDRV_O_CACHE_WB unconditionally, the flag is removed now. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>
