Fix open-network-stream responsiveness

Problem reported by Christer Ekholm (Bug#23864).
Backport from master.
* src/process.c (wait_reading_process_output):
Fix typo introduced in 2015-07-06T02:19:13Z!eggert@cs.ucla.edu
when wait == INFINITY and got_output_end_time is invalid.
In this case the code should break, not continue.
