hinic: avoid gcc -Wrestrict warning
With extra warnings enabled, gcc complains that snprintf should not
take the same buffer as source and destination:
drivers/net/ethernet/huawei/hinic/hinic_ethtool.c: In function 'hinic_set_settings_to_hw':
drivers/net/ethernet/huawei/hinic/hinic_ethtool.c:480:9: error: 'snprintf' argument 4 overlaps destination object 'set_link_str' [-Werror=restrict]
480 | err = snprintf(set_link_str, SET_LINK_STR_MAX_LEN,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
481 | "%sspeed %d ", set_link_str, speed);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/huawei/hinic/hinic_ethtool.c:464:7: note: destination object referenced by 'restrict'-qualified argument 1 was declared here
464 | char set_link_str[SET_LINK_STR_MAX_LEN] = {0};
Rewrite this to avoid the nested sprintf and instead use separate
buffers, which is simpler.
