When CONFIG_NET_SCHED or CONFIG_NET_RX_BUSY_POLL is /not/ set and we try a narrow __sk_buff load of tc_index or napi_id, respectively, then verifier rightfully complains that it's misconfigured, because we need to set target_size in each of the two cases. The rewrite for the ctx access is just a dummy op, but needs to pass, so fix this up.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
