Subject: [PATCH] usb: host: xhci: simplify irq handler return

commit 76a35293b901915c5dcb4a87a4a0da8d7caf39fe upstream.

Instead of having several return points, let's use a local variable and
a single place to return. This makes the code slightly easier to read.

[set ret = IRQ_HANDLED in default working case  -Mathias]
