power: max17048: fix crash if battery not recognised

probe() calls max17048_check_battery() which returns
an error if battery version is not correct.  This
check returns a int but probe() uses return value
as unsigned.  This causes version<0 check to not
work.

fixed return goto on error as code was calling
power_supply_unregister() twice on error.

This fixes the kernel crash I was seeing.
