perf data: Fix sentinel setting for data_cmds array

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 ]
