Whenever I am running the command sudo service varnish restart it shows the following message

* Stopping HTTP accelerator varnishd                                    [fail]
* Starting HTTP accelerator varnishd                                    [fail]

You have a syntax error in your configuration file. You need to fix that. 

Expected '.' got 'sub'
program line 98), at
('input' Line 11 Pos 1)

means that the error is in line 11 of the configuration file (using a editor which displays line numbers can be very useful):

  1.  # This is a basic VCL configuration file for varnish.  See the vcl(7)
  2.  # man page for details on VCL syntax and semantics.
  3.  #
  4.  # Default backend definition.  Set this to point to your content
  5.  # server.
  6.  #
  7.  backend default {
  8.      .host = "127.0.0.1";
  9.      .port = "8080";
 10.  # Drop any cookies sent to Wordpress.
 11.  sub vcl_recv {
 12.          if (!(req.url ~ "wp-(login|admin)")) {
 13.                  unset req.http.cookie;
 14.         }

Seems that at line 11. sub vcl_recv { somebody is trying to define a VCL subroutine within a backend specification, which is not a valid syntax...
