A undefined value was being used for the OLD_RING_BUFFER_TYPE_TIME_STAMP
case entry, as the 'length' variable was not being initialized, fix it.
Caught by the reporter when building tools/perf/ using clang, which emmitted
this warning:
kbuffer-parse.c:312:7: warning: variable 'length' is used uninitialized whenever switch case is taken [-Wsometimes-uninitialized]
case OLD_RINGBUF_TYPE_TIME_EXTEND:
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
kbuffer-parse.c:339:29: note: uninitialized use occurs here
kbuf->next = kbuf->index + length;
^~~~~~
kbuffer-parse.c:297:21: note: initialize the variable 'length' to silence this warning
unsigned int length;
