ext3: don't inherit inappropriate inode flags from parent
At present INDEX is the only flag that new ext3 inodes do NOT inherit from
their parent. In addition prevent the flags DIRTY, ECOMPR, IMAGIC and
TOPDIR from being inherited. List inheritable flags explicitly to prevent
future flags from accidentally being inherited.
This fixes the TOPDIR flag inheritance bug reported at
http://bugzilla.kernel.org/show_bug.cgi?id=9866.
