If multiple Reported-by: tags are used, the
checkpatch script throws a false positive warning
even when there is a Closes tag following the two
tags. This fix checks if the closes tag is present
after multiple Reported-by tags.

Here is an example of the same:
> WARNING: Reported-by: should be immediately followed by Closes: with a
> URL to the report
> #10:
> Reported-by: Kernel test bot <ppppqqqq@ymail.com>
> Reported-by: Some Person <xxxyyy@gmail.com>

> total: 0 errors, 1 warnings, 0 checks, 8 lines checked
