[PATCH iproute2 2/2] netem: Fix 'reorder' section of man page

[Vijay Subramanian <subramanian.vijay@gmail.com>]

The syntax used in the example on reordering in the manpage is inconsistent with
the usage syntax.  Moreover, the text does not describe the reordering process
in the kernel correctly. This patch fixes these two issues.
