[Mesa-dev] [PATCH 12/12] intel/decoder: mark result as MAYBE_UNUSED in gen_field_iterator_next

[Kai Wasserbäch]

Only used, when asserts are enabled.

Fixes an unused-variable warning with GCC 8:
 ../../../src/intel/common/gen_decoder.c: In function 'gen_field_iterator_next':
 ../../../src/intel/common/gen_decoder.c:1008:12: warning: unused variable 'result' [-Wunused-variable]
        bool result = iter_decode_field(iter);
             ^~~~~~
