LU-9033 llite: don't zero timestamps internally
In ll_md_blocking_ast(), we zero all timestamps to avoid these
'leftovers' interfering the new timestamps from MDS, especially
when the timestamps are set back by other clients. It's not
quite right to change timestamps in this way, because:
1. The pending lock can be matched by getattr, so these zero
timestamps can be fetched by application in a small race window.
2. It doesn't make sense to zero the mtime and ctime, because we
always use the newest ctime and mtime from MDS when do attributes
merge, they won't interfere new timestamps set by other clients.
