subscr_name(): Handle case for subscr == NULL

subscr_name() was called from several places:
* either without a check for subscr being NULL, which for example
  was causing a segfault if we hand-over a channel before identifying the
  subscriber
* or with an explicit NULL check and the ternary operator (?).

We now simplify the code by checking for the NULL Subscriber in subscr_name()
itself.
