Fixup r240246: hwpmc needs to retain the pinning until ASTs are not
executed. This means past the point where userret() is generally
executed.

Skip the td_pinned check if a callchain tracing is currently happening
and add a more robust check to pmc_capture_user_callchain() in order to
catch td_pinned leak past ast() in hwpmc case.
