Subject: [PATCH net] hinic: fix passing non negative value to ERR_PTR

get_dev_cap and set_resources_state functions may return a positive
value because of hardware failure, and the positive return value
can not be passed to ERR_PTR directly.

Fixes: 7dd29ee12865 ("net-next/hinic: add sriov feature support")
