Subject: [char-misc fix for 3.5] mei: pci_resume: set IRQF_ONESHOT for msi request_threaded_irq

when the default irq quick handler is used then IRQF_ONESHOT must be set
otherwise the request fails and following error is displayed:

mei 0000:00:16.0: irq 48 for MSI/MSI-X
genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 48
mei 0000:00:16.0: request_threaded_irq failed: irq = 48.
dpm_run_callback(): pci_pm_resume+0x0/0x140 returns -22
PM: Device 0000:00:16.0 failed to resume async: error -22
