    cluster/ec: Fix invalid __fd_unref() call

    __fd_unref() doesn't do any cleanup, so it cannot be called to release
    fd references, specially if it's the last reference.

    The code has been changed to avoid a call to this function.

    In the previous version we always tried to keep the newest fd in the
    ec_lock_t structure. However this is not necessary. We'll always keep
    one reference to an open file on the same inode. It's irrelevant if
    the reference is new or old.

    The function __fd_unref() has also been removed from fd.h to avoid being
    used in the future since it's useless as it's defined now.
