MFD/Battery: Fix battery status setting logic for interrupt case

BZ: 38168

Right we are setting the battery status to Not Chargring upon certain
interrutps without properly(really) checking the charger fault condition.

This patch will fix this issue by making sure that we check charger
fault case AND interrupt bits.
