Jan Höppner 3d74c534bf libdasd: Fix flag for opening read-only devices ...

dasd_is_ro() uses the O_RDWR flag when opening the file descriptor.
However, an attempt to open the file descriptor of a device that is in
read-only state will fail and the BLKROGET ioctl that is used to
actually determine the read-only state can't be issued.
Change the flag to O_RDONLY to fix this.
