In preparation for moving OSD request allocation and submission into
object request state machines, get rid of RBD_OBJ_WRITE_{FLAT,GUARD}.
We would need to start in a new state, whether the request is guarded
or not. Unify them into RBD_OBJ_WRITE_OBJECT and pass guard info
through obj_req->flags.
While at it, make our ENOENT handling a little more precise: only hide
ENOENT when it is actually expected, that is on delete.

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.
