x86, bts: remove bad warning
In case a ptraced task is reaped (while the tracer is still attached), ds_exit_thread() is called before ptrace_exit(). The latter will release the bts_tracer and remove the thread's ds_ctx. The former will WARN() if the context is not NULL. Oleg Nesterov submitted patches that move ptrace_exit() before exit_thread() and thus reverse the order of the above calls. Remove the bad warning. I will add it again when Oleg's changes are in.
