    nettrace_3gpp_32_423: fix memleak and copy of uninitialized memory
    
    When protocol="map", but the name attribute value is invalid, a memleak
    occurs. Observe also that dissector_table_str is 22 bytes (21 characters
    plus nul) and rounding up to a multiple of 4 means that 2 bytes of
    uninitialized memory could be copied. Avoid that by copying the actual
    length. Memory leak was found by Clang Static Analyzer.
