This function disconnects any qpairs that match both
the listen trid and the subsystem pointer. If the
specified subsystem is NULL, it will just disconnect
all qpairs matching the listen trid.
But there are cases where a qpair doesn't yet have an
associated subsystem - for example, before a CONNECT
is received.
Currently we would always disconnect such a qpair, even
if a subsystem pointer is passed. Presumably this check
was added to ensure we don't dereference qpair->ctrlr
when it is NULL but it was added incorrectly.
Also while here, move and improve the comment about
skipping qpairs.
