Cornelia Huck bddabeb71f vfio: ccw: process ssch with interrupts disabled

commit 3368e547c52b96586f0edf9657ca12b94d8e61a7 upstream.

When we call ssch, an interrupt might already be pending once we
return from the START SUBCHANNEL instruction. Therefore we need to
make sure interrupts are disabled while holding the subchannel lock
until after we're done with our processing.
