[PATCH net-next 2/2] docs: networking: Fix failover build warnings

["Tobin C. Harding" <me@tobin.cc>]

Currently building the net_failover docs causes a bunch of warnings to
be emitted.  These warnings are all related to indentation and correctly
highlight missing '::' (for code sections).  It looks, from other rst
files in Documentation, that the first column should be indented 2
spaces.

Add '::' before code snippets and indent all snippets uniformly starting
with 2 spaces.

Cc'd Jon incase he wants to suggest a preferred level of indentation.

thanks,
Tobin.
