In preparation for deep-flatten feature, stop copying num_osd_ops from
the original request in rbd_obj_issue_copyup(). Split the calculation
into count_{write,zeroout}_ops() respectively and determine whether the
assert_exists guard is needed with the new rbd_obj_copyup_enabled().
As a nice side effect, we no longer guard in the writefull case as the
copyup'ed object is always fully overwritten.

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.
