wl3501_cs: min_t() cast truncates high bits
wrqu->encoding.length comes from the network administrator. It's
size u16. We want to limit "tocopy" to the smallest value of either
"len_keys", "wrqu->encoding.length" or 100. But because .length
gets cast from u16 to u8 we might use a random, smaller value than
the was desired. It's probably not very serious, but we may as well
fix it.
Btw, this is from code auditing and not from testing. I don't know
if this affects anyone in real life.
