Whenever query statistics is issued for trap with DROP action, devlink subsystem would also fill-in statistics 'dropped' field. In case if device driver did't register callback for hard drop statistics querying, 'dropped' field will be omitted and not filled. Add trap_drop_counter_get callback implementation to the netdevsim. Add new test cases for netdevsim, to test both the callback functionality, as well as drop statistics alteration check.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
