Joseph Koshy 6fe00c7876 - Bug fix: prevent a thread from migrating between CPUs between the
time it is marked for user space callchain capture in the NMI
  handler and the time the callchain capture callback runs.

- Improve code and control flow clarity by invoking hwpmc(4)'s user
  space callchain capture callback directly from low-level code.
