      Make target mounting with "-o rdonly_dev" work.

       "rdonly_dev"  currently does not work. While the "rdonly_dev" returns "Operation not supported" from OSD. It is a simple flag check which is doing the returning, removing the check seems to work.

      Mounting with "rdonly_dev" 

      # umount /mnt/lustre-mds1
# mount.lustre /dev/mapper/mds1_flakey /mnt/lustre-mds1 -o rdonly_dev
mount.lustre: mount /dev/mapper/mds1_flakey at /mnt/lustre-mds1 failed: Operation not supported
