wifi: hostap: fix stringop-truncations GCC warning
With GCC 13.1 and W=1 hostap has a warning:
drivers/net/wireless/intersil/hostap/hostap_ioctl.c:3633:17: warning: 'strncpy' specified bound 16 equals destination size [-Wstringop-truncation]
fortify-string.h recommends not to use strncpy() so use strscpy() which fixes
the warning. Also now it's guarenteed that the string is NUL-terminated.
Compile tested only.
