nl80211 vendor netlink dumpit, like netlink_callback->dump, should signal successful completion by returning 0. Currently, that will just cause dumpit to be called again, possibly many times until an error occurs. Since skb->len is never going to be 0 by the time dumpit is called, the only way for dumpit to signal completion is by returning an error. If it returns a positive value, the current message is cancelled, but that positive value is returned and nl80211_vendor_cmd_dump gets called again. Fix that by passing a return value of 0 through.

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.
