The recent new patch "perf tools: Add new 'perf data' command" (commit
2245bf14 in acme's git repo perf/core) has caused a building error when
compiling the source code of perf:
cc1: warnings being treated as errors
builtin-data.c:89: error: missing initializer
builtin-data.c:89: error: (near initialization for ‘data_cmds[1].summary’)
make[2]: *** [builtin-data.o] Error 1
make[2]: *** Waiting for unfinished jobs....
LD bench/perf-in.o
LD tests/perf-in.o
make[1]: *** [perf-in.o] Error 2
make: *** [all] Error 2
This patch fixes the building error above.

[ .name == NULL ends the loop, use it instead of seting all fields to NULL ]
