DAMON core prints error messages when damon_target object creation is failed or wrong monitoring attributes are given. Because appropriate error code is returned for each case, the messages are not essential. Also, because the code path can be triggered with user-specified input, this could result in kernel log mistakenly being messy. To avoid the case, this commit removes the messages.

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.
