Revert "MEDIUM: queue: make pendconn_process_next_strm() only return the pendconn"

This reverts commit 5304669e1b1a213d2754755a47735ecd5549ce7b.

The recent changes since 5304669e1 MEDIUM: queue: make
pendconn_process_next_strm() only return the pendconn opened a tiny race
condition between stream_free() and process_srv_queue(), as the pendconn
is accessed outside of the lock, possibly while it's being freed. A
different approach is required.
