genirq/manage: Use the correct lock guard in irq_set_irq_wake() 

Commit 8589e325ba ("genirq/manage: Rework irq_set_irq_wake()") updated
the irq_set_irq_wake() to use the new guards for locking the interrupt
descriptor.

However, in doing so it inadvertently changed irq_set_irq_wake() such that
the 'chip_bus_lock' is no longer acquired. This has caused system suspend
tests to fail on some Tegra platforms.

Fix this by correcting the guard used in irq_set_irq_wake() to ensure the
'chip_bus_lock' is held.
