mount(8) only uses realpath() for the mountpoint, so don't look up the

real path here for the mount device (or path).  This fixes difficulties
unmounting devices that are actually symlinks to real devices.

Also, print the original path instead of the real path in early error
messages.  nfs path handling and later error messages may still be wrong,
probably only in silly cases where the original path is both a symlink
and a remote path.
