power: supply: bq27xxx: Report charge full state correctly

Browse Source 
When reporting the charging status, the existing code reports the battery
as full only when the reported current flowing is exactly 0mA, which is
unlikely in practice.

Fix the reporting by giving priority to the battery's full state
indication/flag.

Tested on the Nokia N900 with bq27200 fuel gauge.
