This fixes memory and shm file descriptor leakage that occurred when a large request body was passed via shared memory. The leakage was caught with the "test_settings_body_buffer_size" test. The main condition is the "body_buffer_size" value exceeding 10 Mb (a shm segment). Thus, the router was forced to split the body into several shm segments, but these buffers were not freed because of dummy completion handlers.
