Try to unshare an extent before granting a lease to pnfs; if this isn't
possible, then bail out.

I don't like this at all.  The block and scsi layout protocols actually
have support for reflinks, someone just needs to implement it..

But until that is implemented I'd rather fail getting a layout than
starting a potentially very long running unshare.

Fair enough, I'll dump this one.
