Ticket 48311 - nunc-stans: Attempt to release connection that

  is not acquired

Bug Description:  ns_connection_post_io_or_closing() was not aquiring the
                  connection in the optimized build, which led to the connection
                  ref count getting out sequence.

Fix Description   Do not call connection_acquire_nolock() inside a PR_ASSERT call.

                  Also changed other PR_ASSERTs to only be called if DEBUG is set
