Tommi Rantala db2e581fe9 perf: Treat attr.config as u64 in perf_swevent_init() ...

BugLink: http://bugs.launchpad.net/bugs/1173170

commit 8176cced70 upstream.

Trinity discovered that we fail to check all 64 bits of
attr.config passed by user space, resulting to out-of-bounds
access of the perf_swevent_enabled array in
sw_perf_event_destroy().

Introduced in commit b0a873ebb ("perf: Register PMU
implementations").
