LU-15106 ofd: quiet deprecated param warning

There are a number of obdfilter parameter files that report a
warning even when they are read, which is confusing for users
if there is a tool that is scraping all available parameters:

    # lctl get_param obdfilter.*.*
    ofd: 'obdfilter.*.read_cache_enabled' is deprecated,
         use 'osd-*.read_cache_enabled' instead
    ofd: 'obdfilter.*.readcache_max_filesize' is deprecated,
         use 'osd-*.readcache_max_filesize' instead
    ofd: 'obdfilter.*.sync_on_lock_cancel' is deprecated,
         use 'obdfilter.*.sync_lock_cancel' instead
    ofd: 'obdfilter.*.writethrough_cache_enabled' is deprecated,
         use 'osd-*.writethrough_cache_enabled' instead

It should only print a message if the parameters are actually written.
Also fix the messages to reference the correct parameter names.

Most of these parameter links were added in 2.4 with the addition of
osd-ldiskfs.  However, the deprecation warnings were only added in
2.12.53 and slated for removal in 2.15, but were not backported to
2.12 LTS, and there hasn't been an LTS release since then, so it is
better bump removal so the upcoming 2.15 LTS release includes them.

Fix the test scripts to only use the new parameter names, to avoid
spurious warning messages.  We don't test interop with 2.3 anymore.

Test-Parameters: trivial
Fixes: 7df7347b7b18 ("LU-12967 ofd: restore sync_on_lock_cancel tunable")
Fixes: 493cd8088388 ("LU-8066 osd: migrate from proc to sysfs")
