    drm/xe/oa: Fix overflow in oa batch buffer
    
    By default xe_bb_create_job() appends a MI_BATCH_BUFFER_END 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 MI_BATCH_BUFFER_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) <= size` failed!
                   platform: LUNARLAKE subplatform: 1
                   graphics: Xe2_LPG / Xe2_HPG 20.04 step B0
                   media: Xe2_LPM / Xe2_HPM 20.00 step B0
                   tile: 0 VRAM 0 B
                   GT: 0 type 1
    
    So here checking if batch buffer already have MI_BATCH_BUFFER_END if
    not append it.
    
    v2:
    - simply fix, suggestion from Ashutosh
