Move all the owner setting code closer to the rwsem-xadd fast paths directly within rwsem.h file as well as in the slowpaths where owner setting is done after acquring the lock. This will enable us to add DEBUG_RWSEMS check in a later patch to make sure that read lock is really acquired when rwsem_down_read_failed() returns, for instance.

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.
