power: supply: core: repair kernel-doc for power_supply_vbat2ri()

The function power_supply_vbat2ri() does not have a parameter called table,
despite it being mentioned in the kernel-doc comment. The table is actually
obtained from the info parameter, the battery information container. Hence,
./scripts/kernel-doc -none drivers/power/supply/power_supply_core.c warns
about this excess function parameter.

Adjust the kernel-doc comment for power_supply_vbat2ri() for make W=1
happiness.
