<Sigh>

I think we need to get kernel patches into mainline ASAP not to set
the EXTENTS_FL --- be conservative in what you send --- and at least
for now, e2fsck needs to accept (and not complain or core dump) if
EXTENTS_FL is set for files where ext2fs_inode_has_valid_blocks()
returns false --- be liberal in what you accept.  

Eventually, after the kernel patches hit mainline, we could change
e2fsck to automatically fix all of these in preen mode, just for
cleanliness sake.
