lan78xx: replace deprecated strncpy 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.
Other implementations of .*get_drvinfo use strscpy so this patch brings
lan78xx_get_drvinfo() in line as well:
igb/igb_ethtool.c +851
static void igb_get_drvinfo(struct net_device *netdev,
igbvf/ethtool.c
167:static void igbvf_get_drvinfo(struct net_device *netdev,
i40e/i40e_ethtool.c
1999:static void i40e_get_drvinfo(struct net_device *netdev,
e1000/e1000_ethtool.c
529:static void e1000_get_drvinfo(struct net_device *netdev,
ixgbevf/ethtool.c
211:static void ixgbevf_get_drvinfo(struct net_device *netdev,
