usb: xhci: Fix compare to use physical addresses in xhci_bulk_tx()

Browse source 
Testing with v2021.01 on MIPS Octeon has shown, that the latest patch
for the "short packet event trb handling" did introduce a bug on
platforms with virtual address != physical address. This patch fixes
this issue by using the correct address types in the compare (both
physical in this case).
