PHC gets initialized in nsim_init_netdevsim(), which
is only called if (nsim_dev_port_is_pf()).
Create a counterpart of nsim_init_netdevsim() and
move the mock_phc_destroy() there.
This fixes a crash trying to destroy netdevsim with
VFs instantiated, as caught by running the devlink.sh test:
BUG: kernel NULL pointer dereference, address: 00000000000000b8

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.
