Annoying free inode warnings

[Jeff Bailey]

Roland, et al.,

Would you accept a patch to add a configure option that removes the
annoying 'free inode' warning messages?  I can set it on by default,
if you'd like.

My final preference would be to leave it disabled until e2fsck is
willing to fix the problem when the FS is checked with -f, but having
a reasonable way to disable it for now would be enough.

Tks,
Jeff Bailey
