When csi scheduling and retransmission meet, check whether the bit rate of retransmission pdsch is greater than 0.95

When csi and pdsch met, there was only the New Tx Deal

dlsch_information srsran::get_dlsch_information(const dlsch_configuration& config)
{
......
// Count number of RE used for CSI-RS.
unsigned nof_re_csi_rs_per_rb = 0;

// Count number of RE used for PT-RS.
unsigned nof_pt_rs_per_rb = 0;

// Count total number of resource elements available for DL-SCH.
unsigned nof_re_dl_sch =
config.nof_rb * (config.nof_symbols * NRE - nof_re_dmrs_per_rb - nof_re_csi_rs_per_rb - nof_pt_rs_per_rb);

}
The re of csi and ptrs is not actually removed during pdsch rate check
