cam: Only queue the exact number of requests asked for

The cam option --capture=N is suppose to only capture N requests. But if
the processing done for each request is large (such as writing it to a
slow disk) the current implementation could queue more than N requests
before the exit condition is detected and capturing stopped.

Solve this by only queueing N requests while still waiting for N
requests to complete before exiting.
