PMBus: Fix "file" name for STATUS_FANS_1_2

While attempting to look into creating and detecting power supply fan
faults, I noticed that we were attempting to read status0_fans12, but
the actual file name is status0_fan12.

Verified same file name difference/issue on Witherspoon with 5.14.6
kernel.

Tested:
    Debug commands on Witherspoon for fan fault.
    Note lack of status0_fan12 in verbose journal entry:
     MESSAGE=The power supply detected bad fan operation.
     TRANSACTION_ID=3237897146
     RAW_STATUS=STATUS_WORD=0x400|status0_mfr=0x0|status0_temp=0x0
     CALLOUT_INVENTORY_PATH=/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply1
     SYSLOG_IDENTIFIER=psu-monitor
    Bitbake build phosphor-power with change.
    Overlay patch same Witherspoon system.
    Debug commands for fan fault results in expected journal entry:
     MESSAGE=The power supply detected bad fan operation.
     TRANSACTION_ID=3549612893
     RAW_STATUS=STATUS_WORD=0x400|status0_mfr=0x0|status0_temp=0x0|status0_fan12=0x20
     CALLOUT_INVENTORY_PATH=/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply1
