Remove no-op code from linux_proc

[Martins Innus <minnus@xxxxxxxxxxx>]

Hi,
    In my initial dynamic procs submission, I had a copy and paste 
error that didn't do anything. cgroups must have returned a value if the 
metrics makeup changed.  Proc only returns non-zero when /proc can't be 
opened.  From:

    Remove noop code
    In my initial dynamic proc refractor, I copied an unneccessary call 
that was in the cgroups code.
    For the procs case, it is not needed and never gets called.
