Shuah Khan (Samsung OSG) 81f7567c51 usb: usbip: Fix BUG: KASAN: slab-out-of-bounds in vhci_hub_control() 
vhci_hub_control() accesses port_status array with out of bounds port
value. Fix it to reference port_status[] only with a valid rhport value
when invalid_rhport flag is true.

The invalid_rhport flag is set early on after detecting in port value
is within the bounds or not.

The following is used reproduce the problem and verify the fix:
