power_supply: lp8788-charger: Fix leaked power supply on probe fail

Browse Source 
commit a7117f81e8391e035c49b3440792f7e6cea28173 upstream.

Driver forgot to unregister charger power supply if registering of
battery supply failed in probe(). In such case the memory associated
with power supply leaked.
