sfc: handle error pointers returned by rhashtable_lookup_get_insert_fast()
 
Several places in TC offload code assumed that the return from
 rhashtable_lookup_get_insert_fast() was always either NULL or a valid
 pointer to an existing entry, but in fact that function can return an
 error pointer.  In that case, perform the usual cleanup of the newly
 created entry, then pass up the error, rather than attempting to take a
 reference on the old entry.

README 
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.
