Jan Glauber 5f4026f8b2 [S390] qdio: prevent dsci access without adapter interrupts
A kernel panic may occur during sending or receiving network packets
on a machine without adapter interrupts since commit d36deae.
The bug is triggered by writing to the shared indicator address which
is set to 0 if the machine doesn't have adapter interrupts.

Make the reading and setting of the shared indicator dependent on the
adapter interrupt feature and while at it move the code to the
file containing the adapter interrupt related code.

Thanks to Jan Jaeger for tracking this down.
