When a subchannel becomes pending with unit exception, start
pending (and for that matter, halt or clear pending) are not
removed in the actl. Device active and subchannel active,
however, are (due to the subchannel becoming status pending
with primary respectively secondary status).

The other conditions in the actl are only cleared when the
guest executes tsch on the subchannel.
