[PATCH] oprofile, arm: proper release resources on failure

[Robert Richter]

Will,

the patch below fixes a resource leak I found during code review. Can
you please review and test it (I don't have an ARM environment for
this available). If you are fine with the change, please ack. I want
to send it upstream via tip/perf/urgent.

Though you reworked the code already, parts of the fix are still valid
for latest oprofile code in oprofile/core.

Ingo,

if Will agrees with it, please apply it directly to tip/perf/urgent.

Thanks,

-Robert
