[PATCH v3 6/8] perf record: Fix a potential error handling issue

[Namhyung Kim <namhyung@kernel.org>]

The evlist is allocated at the beginning of cmd_record().  Also free-ing
thread masks should be paired with record__init_thread_masks() which is
called right before __cmd_record().

Let's change the order of these functions to release the resources
correctly in case of errors.  This is maybe fine as the process exits,
but it might be a problem if it manages some system-wide resources that
live longer than the process.
