power: supply: qcom_battmgr: fix battery chemistry strncmp length

Browse source

The battery_chemistry field is a 4-byte array without guaranteed null
termination. Using BATTMGR_CHEMISTRY_LEN (4) as the strncmp length for
3-character string literals implicitly requires chemistry[3] == '\0',
which may not hold. Use 3 instead to match only the significant bytes.
