USB: UHCI: fix IRQ race during initialization
commit 0f815a0a700bc10547449bde6c106051a035a1b9 upstream.
This patch (as1644) fixes a race that occurs during startup in
uhci-hcd. If the IRQ line is shared with other devices, it's possible
for the handler routine to be called before the data structures are
fully initialized.
The problem is fixed by adding a check to the IRQ handler routine. If
the initialization hasn't finished yet, the routine will return
immediately.
