When we are in connection recovery and the internal command timer on a

have been subsequently reaped due to the connection recovery. This can
cause
one or both of the pointers above to be NULL and cause a system crash
if we try
to return the command to the midlayer.
Instead, double check the pointers before the return to the midlayer so
as to
prevent the crash and let the upper layers finish the session recovery
and
rediscover the device.
