[PATCH net-next] net: Space: Replace memset(0) + strscpy() with strscpy_pad()

[Thorsten Blum]

Replace memset(0) followed by strscpy() with strscpy_pad() to improve
netdev_boot_setup_add(). This avoids zeroing the memory before copying
the string and ensures the destination buffer is only written to once,
simplifying the code and improving efficiency.
