s390x/3270: fix instruction interception handler 

Commit bab482d740 ("s390x/css: ccw translation infrastructure")
introduced instruction interception handler for different types of
subchannels. For emulated 3270 devices, we should assign the virtual
subchannel handler to them during device realization process, or 3270
will not work.

Fixes: bab482d740 ("s390x/css: ccw translation infrastructure")
