Frederic Weisbecker 3928ddbe99 perf record: Fix unhandled io return value 
Building latest perfcounter fails on the following error:

 builtin-record.c: In function ‘create_counter’:
 builtin-record.c:451: erreur: ignoring return value of ‘read’, declared with attribute warn_unused_result
 make: *** [builtin-record.o] Erreur 1

Just check if we successfully read the perf file descriptor.
