is referenced when set

is the number of requests segments that still can be submitted to the controller without overloading it. It is initialized to descr->wRequests when aiming.

A rpipe supports a max of descr->wRequests at the same time; before submitting seg_lock has to be taken. If segs_avail > 0, then we can submit; if not, we have to queue them.
