USB: xhci: unsigned char never equals -1
There were some places that compared port_speed == -1 where port_speed
is a u8. This doesn't work unless we cast the -1 to u8. Some places
did it correctly.
Instead of using -1 directly, I've created a DUPLICATE_ENTRY define
which does the cast and is more descriptive as well.
