9169aef by Pascal Quantin (pascal.quantin@xxxxxxxxx):

    HTTP2: prevent a segmentation fault if HTTP2 dissector was not called on first pass
    
    With HTTP2 heuristics to identify the conversation, a packet can be
    skipped on first pass and then decoded as HTTP2 on subsequent ones.
    Check that header data is available before attempting header
    decompression.
