    Remove unused but set variable in cxgb_sge
    
    Clang 15 warns:
    
        sys/dev/cxgb/cxgb_sge.c:1290:21: error: variable 'txsd' set but not used [-Werror,-Wunused-but-set-variable]
                struct tx_sw_desc *txsd = &txq->sdesc[txqs->pidx];
                                   ^
    
    It appears 'txsd' is a leftover from a previous refactoring (see
    3f345a5d09b6), but is no longer used for anything, and can be removed
    without any functional change.
