ext3: force ro mount if ext3_setup_super() fails
If ext3_setup_super() fails i.e. due to a too-high revision,
the error is logged in dmesg but the fs is not mounted RO as
indicated.
Tested by:
[164152.114551] EXT3-fs (sdb6): error: revision level too high, forcing read-only mode
/dev/sdb6 /mnt/test2 ext3 rw,seclabel,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered 0 0
