    i915/gem_exec_parse: Switch to a fixed timeout for basic-allocations

    basic-allocations was written to demonstrate a flaw in our continual
    reallocation of cmdparser shadow bo, largely fixed by keeping a small
    cache of bo of different lengths (to speed up the search for the correct
    sized bo). We only care enough to exercise the slowdown by submitting
    lots of execbufs, and can see the effect of bo caching on the rate, so
    replace the fixed number of iterations with a timeout and count how many
    batches we could submit instead.

    Similarly, we now do not need to wait for all of our queue to complete
    as we can tell the kernel to drop the queue instead.
