power: supply: isp1704: Fix unchecked return value of devm_kzalloc

Function devm_kzalloc() will return a NULL pointer. However, in function
isp1704_charger_probe(), the return value of devm_kzalloc() is directly
used without validation. This may result in a bad memory access bug.

Fixes: 34a109610e2a ("isp1704_charger: Add DT support")
