e1000: 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.

We can see that netdev->name is expected to be NUL-terminated based on
it's usage with format strings:
|       pr_info("%s NIC Link is Down\n",
|               netdev->name);

A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.

This is in line with other uses of strscpy on netdev->name:
$ rg "strscpy\(netdev\->name.*pci.*"

drivers/net/ethernet/intel/e1000e/netdev.c
7455:   strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name));

drivers/net/ethernet/intel/ixgbe/ixgbe_main.c
10839:  strscpy(netdev->name, pci_name(pdev), sizeof(netdev->name));
