power: supply: qcom_battmgr: Ignore extra __le32 in info payload

Browse Source 
Some newer ADSP firmware versions on X1E80100 report an extra __le32 at the
end of the battery information request payload, causing qcom_battmgr to
fail to initialize. Adjust the check to ignore the extra field in the info
payload so we can support both old and newer firmware versions.
