wifi: ath12k: Fix WMI tag for EHT rate in peer assoc

Incorrect WMI tag is used for EHT rate update from host to firmware
while encoding peer assoc WMI.

Correct the WMI tag used for EHT rate update from WMI_TAG_HE_RATE_SET
to the proper tag. This ensures firmware does not mistakenly update HE rate during parsing.

Found during code review. Compile tested only.
