libglusterfs: Even anonymous fds must have fd->flags set
We do not set the same flags to anonymous fd that posix uses to open an anonymous fd in the backend. If there are any xlators which rely on these flags for their operation they may not work well. Add proper flags to anonymous fds at the time of their creation and refer to them for subsequent operations.
