    fs/fat: Reduce stack usage
    
    We have limited stack in SPL builds.  Drop itrblock and move to
    malloc/free of itr to move this off of the stack.  As part of this fix a
    double-free issue in fat_size().

    Rework to use malloc/free as moving this to a global overflows some SH
    targets.
