wlan: fix buffer overflow in linkspeed ioctl

cld to prima propagation.

In linkspeed ioctl handler, mac address array is allocated a
size of MAC_ADDRESS_STR_LEN, which is 18 bytes taking account of null
terminator '\0'. But in code, a null terminator is being manually added
at index MAC_ADDRESS_STR_LEN. This would overflow the buffer and hence
null terminator should be added at MAC_ADDRESS_STR_LEN -1.
