netfs has a number of lists of symbols for use in tracing, listed in an enum and then listed again in a symbol->string mapping for use with __print_symbolic(). This is, however, redundant.
Instead, use the symbol->string mapping list to also generate the enum where the enum is in the same file. Changes ======= ver #3) - #undef EM and E_ at the end of the trace file[1].
