erofs: make filesystem exportable
Implement export operations in order to make EROFS support accessing
inodes with filehandles so that it can be exported via NFS and used
by overlayfs.
Without this patch, 'exportfs -rv' will report:
exportfs: /root/erofs_mp does not support NFS export
Also tested with unionmount-testsuite and the testcase below passes now:
./run --ov --erofs --verify hard-link
For more details about the testcase, see:
