RFR(S): 8016277: Crash in nmethod::is_compiled_by_c1() on x86

I assumed it was there to avoid the call to is_native_method() and a crash. Now that the is_native_method() call is gone, no need to check _method for NULL anymore. If the methods do what their names say they do then I don't see why we would care whether _method == NULL.
That was part of "6912062: disassembler plugin needs to produce symbolic information in product mode" that John pushed.
