LU-17941 ofd: do not copy over filter_fid structure

When a bigger filter_fid has been writen on disk by newer server,
downgraded Lustre would read more data but we need store less to
fit smaller filter_fid structure.

Test-Parameters: serverdistro=el8.10
Fixes: 28c366cee6d ("LU-17218 ofd: improve filter_fid upgrade compatibility")
