crypto: cavium/nitrox - refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We know `hw.partname` is supposed to be NUL-terminated by its later use with seq_printf: | nitrox_debugfs.c +25 | seq_printf(s, " Part Name: %s\n", ndev->hw.partname); Let's prefer a more robust and less ambiguous string interface. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer.
