When exiting vfs_export(), delete the "export" option from
the mount options list with vfs_deleteopt().  At this point, the export
information is saved in mp->mnt_export, so we can delete
the "export" mount option from mp->mnt_optnew and mp->mnt_opt.

This fixes read-write/read-only update mounts (mount -u -o rw, mount -u -o ro)
of NFS exported directories.

For some reason, I could only reproduce the problem with a configuration
supplied by Andre:
- "options QUOTA" enabled in kernel config
- "/ -maproot=root 10.0.1.105" in /etc/exports
