LoongArch: Remove redundant call in update_bp_registers()

In update_bp_registers(), there is a duplicate call to write_wb_reg()
when enabling an execute breakpoint:

    write_wb_reg(CSR_CFG_CTRL, i, 0, CTRL_PLV_ENABLE);
    write_wb_reg(CSR_CFG_CTRL, i, 0, CTRL_PLV_ENABLE);

The two lines are completely identical. Remove the redundant call to
clean up the code and eliminate unnecessary register writes.
