Fix the issues reported by PHP_CodeSniffer

Fixed those PHPCS flags.

A summary must describe what needs to be changed, and eventually why. A screenshot is not sufficient, even in the case a patch/MR is provided.
In the case of bug reports, the steps to reproduce the bug should be provided too. In the case of coding standards issues found using an automatic tool, the report given by that tool must be quoted too, including the arguments passed to that tool, if it is a command line tool.

There are not much details provided about the command used for getting the results in the issue description. It seems like PHP CodeSniffer is used (from the issue title) for generating it. Any way all these warnings and errors were present when I checked with phpcs using Drupal and DrupalPractice as standards. Those are all fixed (and some more) and committed to the repository. In order to test it, one can use the following command. Now its returning an empty result.

$ phpcs --standard=Drupal,DrupalPractice --extensions=php,module,inc,install,test,profile,theme,css,info,txt,md,yml,twig responsive_views_pager/*

Hi @sijumpk,
I have reviewed the module by cloning the issue fork and running the PHPCS command. It appears that all the previous errors and warnings reported by the code sniffer have been addressed; however, some errors still persist.
