When the fr_rx function drops a received frame (because the protocol type is not supported, or because the PVC virtual device that corresponds to the DLCI number and the protocol type doesn't exist), the function frees the skb and returns. The code for freeing the skb and returning is repeated several times, this patch uses "goto rx_drop" to replace them so that the code looks cleaner.

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.
