mount/fuse: report ESTALE as ENOENT

When the inode/gfid is missing, brick report back as an ESTALE
error. However, most of the applications don't accept ESTALE as an
error for a file-system object missing, changing their behaviour.

For eg., rm -rf ignores ENOENT errors during unlink of
files/directories. But with ESTALE error it doesn't send rmdir on a
directory if unlink had failed with ESTALE for any of the files or
directories within it.

Thanks to Ravishankar N <ravishankar@redhat.com>, here is a link as to
why we split up ENOENT into ESTALE and ENOENT.
