liquidio: replace deprecated strncpy/strcpy with strscpy
`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
NUL-padding is not required as drvinfo is memset to 0:
| memset(drvinfo, 0, sizeof(struct ethtool_drvinfo));
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.
