usb: xhci: xhci_bulk_tx: Don't "BUG" when comparing addresses
Octeon uses mapped addresses for virtual and physical memory. It's not
that easy to calculate the resulting addresses here. So let's remove
this BUG_ON() completely, as it's not really helpful.
Please also note, that BUG_ON() is not recommended any more in the Linux
kernel.
