user_namespaces.7: Fixes to example

While toying around with the userns_child_exec example program on the
user_namespaces(7) man page, I noticed two things:

* In the EXAMPLE section, we need to mount the new /proc before
  looking at /proc/$$/status, otherwise the latter will print
  information about the outer namespace's PID 1 (i.e., the real
  init).  So the two paragraphs need to be swapped.

* In the program source, make sure to close pipe_fd[0] in the
  child before exec'ing.

ioctl_userfaultfd.2: Drop some unneeded text

From a conversation with Mike Rapoport:

What does "consistent" mean?
    Actually, I though I've copied this text from Andrea's docs,
    but now I've found out it was my wording and I really don't
    remember now what was my intention for "consistent" :) My
    guess is that I was thinking about atomicity of UFFDIO_COPY,
    or the fact that from the faulting thread perspective the
    page fault handling is the same whether it's done in kernel
    or via userfaultfd...  That said, maybe it'd be better just
    to drop "in a consistent way".
