    smb2: add support for SMB3.1.1 multiple error context responses
    
    This change adds dissectors for all error responses types up to
    SMB3.1.1.
    
    It also fixes "Malformed Packet" errors when dissecting error response
    within compounded packet responses.
    
    SMB2 Error responses are a bit convoluted. Error data can be a list
    of error contexts which themselves can hold an error data field.
    See [MS-SMB2] 2.2.2.1.
    
    Pseudo-grammar summary:
    
    ERROR_RESP := ERROR_DATA
    
    ERROR_DATA := ( ERROR_CONTEXT + )
                | ERROR_STATUS_STOPPED_ON_SYMLINK
    	    | ERROR_SHARE_ID_SHARE_REDIRECT
    	    | ERROR_BUFFER_TOO_SMALL
    
    ERROR_CONTEXT := ... + ERROR_DATA
                   | ERROR_SHARE_ID_SHARE_REDIRECT
