If just a table name was given, nf_tables_dump_rules() continued over the list of tables even after a match was found. The simple fix is to exit the loop if it reached the bottom and ctx->table was not NULL. When iterating over the table's chains, the same problem as above existed. But worse than that, if a chain name was given the hash table wasn't used to find the corresponding chain. Fix this by introducing a helper function iterating over a chain's rules (and taking care of the cb->args handling), then introduce a shortcut to it if a chain name was given.

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.
