ctime: Set mdata xattr on legacy files
Problem: The files which were created before ctime enabled would not have "trusted.glusterfs.mdata"(stores time attributes) xattr. Upon fops which modifies either ctime or mtime, the xattr gets created with latest ctime, mtime and atime, which is incorrect. It should update only the corresponding time attribute and rest from backend Solution: Creating xattr with values from brick is not possible as each brick of replica set would have different times. So create the xattr upon successful lookup if the xattr is not created Note To Reviewers: The time attributes used to set xattr is got from successful lookup. Instead of sending the whole iatt over the wire via setxattr, a structure called mdata_iatt is sent. The mdata_iatt contains only time attributes.
