xHCI: synchronize irq in xhci_suspend()
commit 0029227f1bc30b6c809ae751f9e7af6cef900997 upstream.
Synchronize the interrupts instead of free them in xhci_suspend(). This will
prevent a double free when the host is suspended and then the card removed.
Set the flag hcd->msix_enabled when using MSI-X, and check the flag in
suspend_common(). MSI-X synchronization will be handled by xhci_suspend(),
and MSI/INTx will be synchronized in suspend_common().
This patch should be queued for the 2.6.37 stable tree.
