Krzysztof Kozlowski a6d4ac3f86 power: supply: max17042: handle fails of reading status register 
commit 54784ffa5b267f57161eb8fbb811499f22a0a0bf upstream.

Reading status register can fail in the interrupt handler.  In such
case, the regmap_read() will not store anything useful under passed
'val' variable and random stack value will be used to determine type of
interrupt.

Handle the regmap_read() failure to avoid handling interrupt type and
triggering changed power supply event based on random stack value.
