Markus Metzger e2b371f00a mm, x86, ptrace, bts: defer branch trace stopping 
When a ptraced task is unlinked, we need to stop branch tracing for
that task.

Since the unlink is called with interrupts disabled, and we need
interrupts enabled to stop branch tracing, we defer the work.

Collect all branch tracing related stuff in a branch tracing context.
