posix/ctime: Fix fops racing in updating mtime/atime
In distributed systems, there could be races with fops
updating mtime/atime which could result in different
mtime/atime for same file. So updating them only if
time is greater than the existing makes sure, only
the highest time is retained. If the mtime/atime
update comes from the explicit utime syscall, it is
allowed to set to previous time.
Thanks Xavi for helping in rooting the issue.
