batch: Specify number of relocations to accommodate
Since relocations are variable size, depending upon generation, it is easier to handle the resizing of the batch request inside the BEGIN_BATCH macro. This still leaves us with having to resize commands in a few places - which still need adaption for gen8+. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
