brcmfmac: replace strncpy() by strscpy()

Browse source

The strncpy() may truncate the copied string,
replace it by the safer strscpy().

To avoid below compile warning with gcc 8.2:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:In function 'brcmf_vndr_ie':
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:4227:2:
warning: 'strncpy' output truncated before terminating nul copying 3 bytes from a string of the same length [-Wstringop-truncation]
  strncpy(iebuf, add_del_cmd, VNDR_IE_CMD_LEN - 1);
