fix sdr count when number > 255

- After PR-60906, it will count the fru data and type 12 sensors.
  But when SDR count > 255, there are some problems.

- If the lun of cmd isn't 0, the start position of recordID need to be
  updated.
- Using if condition to add type 12 sensors. Because if sensor number
  + fru device is 254, it will overflow after adding 2 type 12 sensors.
- The type of sdrCount is uint8, which means the maximum value is 255,
  so it needs to break while loop if the count reaches 255.

TEST:
root@bmc:~# ipmitool sdr elist | wc -l
281 => 0x119
root@bmc:~# ipmitool sdr elist all | wc -l
295 => 0x127

Before:
root@bmc:~# ipmitool raw -l 0 0x04 0x20 0x00
 ff 83 c8 56 a2 63
root@bmc:~# ipmitool raw -l 0 0x04 0x20 0x01 ERROR
 27 83 c8 56 a2 63
=> count overflow
root@bmc:~# ipmitool raw -l 1 0x04 0x20 0x00
 1a 83 c8 56 a2 63
root@bmc:~# ipmitool raw -l 1 0x04 0x20 0x01 ERROR
 1c 83 c8 56 a2 63
=> doesn't count the fru data

After:
root@bmc:~# ipmitool raw -l 0 0x04 0x20 0x00
 ff 83 3e 2c a3 63
root@bmc:~# ipmitool raw -l 0 0x04 0x20 0x01

root@bmc:~# ipmitool raw -l 1 0x04 0x20 0x01
 28 83 3e 2c a3 63

If count < 255,
root@bmc:~# ipmitool sdr elist | wc -l
151
root@bmc:~# ipmitool sdr elist all | wc -l
165
root@bmc:~# ipmitool raw -l 0 0x04 0x20 0x00
