Fix rare core dump in BackendIdGetTransactionIds().

BackendIdGetTransactionIds() neglected the possibility that the PROC
pointer in a ProcState array entry is null.  In current usage, this could
only crash if the other backend had exited since pgstat_read_current_status
saw it as active, which is a pretty narrow window.  But it's reachable in
the field, per bug #12918 from Vladimir Borodin.

Back-patch to 9.4 where the faulty code was introduced.
