xhci: check if legacy irq is available before using it as fallback

Move the error check "No MSI-X/MSI found and no IRQ in BIOS" inside
'goto legacy'. It is better to check if the IRQ interrupt is available,
before trying to add a handler. Additionally the aforementioned error
message is much more clear.
