[POWERPC] Fix viodasd geometry calculations
Commit a885c8c4316e1c1d2d2c8755da3f3d14f852528d that introduced the getgeo block device method changed the fallback number of sectors and introduced a bug into the fallback cylinder number calculation. Thanks to Rusty Russell for noticing this. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
