Misono Tomohiro a56fe733f4 hwmon: (acpi_power_meter) Fix potential memory leak in acpi_power_meter_add()
[ Upstream commit 8b97f9922211c44a739c5cbd9502ecbb9f17f6d1 ]

Although it rarely happens, we should call free_capabilities()
if error happens after read_capabilities() to free allocated strings.

Fixes: de584afa5e188 ("hwmon driver for ACPI 4.0 power meters")
