Sarah Sharp f8bbeabc34 xhci: Fix issue with port array setup and buggy hosts. 
Fix two bugs with the port array setup.

The first bug will only show up with broken xHCI hosts with Extended
Capabilities registers that have duplicate port speed entries for the same
port.  The idea with the original code was to set the port_array entry to
-1 if the duplicate port speed entry said the port was a different speed
than the original port speed entry.  That would mean that later, the port
would not be exposed to the USB core. Unfortunately, I forgot a continue
statement, and the port_array entry would just be overwritten in the next
line.

The second bug would happen if there are conflicting port speed registers
(so that some entry in port_array is -1), or one of the hardware port
registers was not described in the port speed registers (so that some
entry in port_array is 0).  The code that sets up the usb2_ports array
would accidentally claim those ports.  That wouldn't really cause any
user-visible issues, but it is a bug.

This patch should go into the stable trees that have the port array and
USB 3.0 port disabling prevention patches.
