LU-9727 lustre: record CLOSE if OPEN was recorded

Record CL_CLOSE events in changelogs only if file was opened in
write mode, or if CL_OPEN was recorded.
Changelogs mask may change between open and close operations,
but this is not a big deal if we have a CL_CLOSE entry with no
matching CL_OPEN. Plus Changelogs mask may not change often.
