    drm/i915: Update reset path to fix incomplete requests
    
    Update reset path in preparation for engine reset which requires
    identification of incomplete requests and associated context and fixing
    their state so that engine can resume correctly after reset.
    
    The request that caused the hang will be skipped and head is reset to the
    start of breadcrumb. This allows us to resume from where we left-off.
    Since this request didn't complete normally we also need to cleanup elsp
    queue manually. This is vital if we employ nonblocking request
    submission where we may have a web of dependencies upon the hung request
    and so advancing the seqno manually is no longer trivial.
