Don't short-circuit interrupt handling when the sc_dying flag is set. Just

Don't short-circuit interrupt handling when the sc_dying flag is set. Just
don't forward reports to the child drivers instead.  This fixes an issue
with hardware that sends an interrupt in response to a reset request when
a level-triggered interrupt is used.  In that case the interrupt would
just keep triggering when we issue a reset when we resume (when sc_dying
is set) since we didn't clear the interrupt condition by reading from the
device.
