Subject: [PATCH] ptrace: __ptrace_unlink: use the ptrace_reparented() helper

Currently __ptrace_unlink() checks list_empty(->ptrace_list) to figure out
whether the child was reparented.  Change the code to use ptrace_reparented()
to make this check more explicit and consistent.

No functional changes.
