power: supply: core: Break capacity loop

commit 51c7b6a0 upstream.

We should not go on looking for more capacity tables after
we realize we have looked at the last one in
power_supply_find_ocv2cap_table().

Fixes: 3afb50d7 ("power: supply: core: Add some helpers to use the battery OCV capacity table")
