pxa-camera: simplify the .buf_queue path by merging two loops

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

pxa_dma_update_sg_tail() is called only once, runs exactly the same loop as the
caller and has to recalculate the last element in an sg-list, that the caller
has already calculated. Eliminate redundancy by merging the two loops and
re-using the calculated pointer. This also saves a bit of performance which is
always good during video-capture.
