drm/xe/oa: Fix overflow in oa batch buffer
By default xebbcreatejob() appends a MIBATCHBUFFEREND to batch buffer, this is not a problem if batch buffer is only used once but oa reuses the batch buffer for the same metric and at each call it appends a MIBATCHBUFFER_END, printing the warning below and then overflowing.
[ 381.072016] ------------[ cut here ]------------ [ 381.072019] xe 0000:00:02.0: [drm] Assertion
bb->len * 4 + bb_prefetch(q->gt) <= sizefailed! platform: LUNARLAKE subplatform: 1 graphics: Xe2LPG / Xe2HPG 20.04 step B0 media: Xe2LPM / Xe2HPM 20.00 step B0 tile: 0 VRAM 0 B GT: 0 type 1So here checking if batch buffer already have MIBATCHBUFFER_END if not append it.
