    Fix coverity integer overflow warning

    There seemed to be a mismatch in the datatype of argument `eob` in the
    functions `warehouse_efficients_txb()`and `av1_get_nz_map_contexts()`,
    leading to integer overflow warning. This patch corrects the same.

    Fixes Coverity defect CID 560140: Insecure data handling
    (INTEGER_OVERFLOW)

    Bug: 505436291
    Change-Id: Ibd42ca1b38f97b754a8ef26d65b000d8839b7067
