'commit_schemes_quota_goals' command handler, damos_sysfs_set_quota_scores() assumes the number of schemes sysfs directory will be same to the number of schemes of the DAMON context. The assumption is wrong since users can remove schemes sysfs directories while DAMON is running. In the case, illegal memory accesses can happen. Fix it by checking the case.

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.
