Subject: perf/core: Don't leak event in the syscall error path

From: Alexander Shishkin <[email protected]>

commit 201c2f85bd0bc13b712d9c0b3d11251b182e06ae upstream.

In the error path, event_file not being NULL is used to determine whether the event itself still needs to be free'd, so fix it up to avoid leaking.
