[fanctrl] Fix fanctrl crash when system thermal direction is unknown

[pphuchar]

- What I did
Fix fan control bug that causes segmentation fault when system P/N is not recognized by it.
Update the following component P/N of F2B airflow models:

1. Product PN(TLV): R1241-F9019-01
2. FANs PN(FRU): R1241-FN019-013JW
3. PSU PN(FRU): DPS-1100FB

- How I did it
Handle the case when system P/N is not recognized by set fan speed to max and exit the program.
Add error log about unrecognize P/N in the system log.

- How to verify it
Change System P/N in TLV EEPROM to something else like "EMPTY" or remove P/N feild.
Then run service fanctrl restart the fand_v2 MUST not crash.
An error about unrecognized system P/N logged in the system log.

Look good, Can you attach a test log when service work as normal ?

Still waiting for a new FANs/PSUs FRU image...

Normal running with F2B fans and a psu.
