perf bench: The do_run_multi_threaded() function must use IS_ERR(perf_session__new())
[ Upstream commit e4d71f79cf5c10fa8bc6f5d3bebea570c9c438f1 ]
In case of error, the function perf_session__new() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR()
Committer notes:
This wasn't compiling due to an extraneous '{' not matched by a '}', fix
it.
Fixes: 13edc237200c ("perf bench: Add a multi-threaded synthesize benchmark")
