    mm/mempool: Fix interrupt pool backtrace walk
    
    The interrupt pool backtrace iterator cast the pool base before adding byte
    offsets, so pointer arithmetic was scaled by the backtrace structure size.
    Keep the arithmetic byte-based so the iterator visits the metadata stored
    after each block.
