perf record: Fix possible incorrect free in record__switch_output()
[ Upstream commit aff10a165201f6f60cff225083ce301ad3f5d8f1 ]
perf_data__switch() may not assign a legal value to 'new_filename'.
In this case, 'new_filename' uses the on-stack value, which may cause a
incorrect free and unexpected result.
Fixes: 03724b2e9c45 ("perf record: Allow to limit number of reported perf.data files")
