[PATCH] proc_net macro's for non-proc-fs case

[Stephen Hemminger <shemminger@xxxxxxxx>]

The following should work better. They have the desired properties that:
        - return value makes sense for those that might check
        - arguments fops and info don't have to be defined (ie can be #ifdef'd 
out)
        - generate no warnings for null effect.
