Fix missing initialization of ts_info->phc_index in the dump command,
which could cause a netdev interface to incorrectly display a PTP provider
at index 0 instead of "none".
Fix it by initializing the phc_index to -1.
In the same time, restore missing initialization of ts_info.cmd for the
IOCTL case, as it was before the transition from ethnl_default_dumpit to
custom ethnl_tsinfo_dumpit.
Also, remove unnecessary zeroing of ts_info, as it is embedded within
reply_data, which is fully zeroed two lines earlier.

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 reStructuredText 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.
