Subject: [PATCH] RDMA/bnxt_re: remove unused num_srqne_processed and num_cqne_processed variables

clang with W=1 reports
drivers/infiniband/hw/bnxt_re/qplib_fp.c:303:6: error: variable
  'num_srqne_processed' set but not used [-Werror,-Wunused-but-set-variable]
        int num_srqne_processed = 0;
            ^
drivers/infiniband/hw/bnxt_re/qplib_fp.c:304:6: error: variable
  'num_cqne_processed' set but not used [-Werror,-Wunused-but-set-variable]
        int num_cqne_processed = 0;
            ^
These variables are not used so remove them.
