sw5100_bms: Return error if GBMS sets float voltage below minimum

This case may happen if a device is connected to the charger with its
input path suspended, since GBMS will send -1 as the float voltage
value to sw5100_bms. sw5100_bms will set the value to the minimum
supported value, which is 3.6V. If VBAT is significantly higher, the
3.6V setting may cause electrical backfeed.

Thus, instead:
- Leave float voltage value as-is.
- Log an error.
- Return -EINVAL to the caller (GBMS).
