perf record: Fix perf.data size in no-buildid mode

The size of perf.data is missing update in no-buildid mode, which gives
wrong output result.

Before this patch:

  $ perf.perf record -B -e syscalls:sys_enter_open uname
  Linux
  [ perf record: Woken up 1 times to  write data ]
  [ perf record: Captured and wrote 0.000 MB perf.data ]

After this patch:

  $ perf.perf record -B -e syscalls:sys_enter_open uname
  Linux
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.001 MB perf.data ]
