mainlining shenanigans

When we succeed in enabling some quota type but fail to enable another one with quota feature, we correctly disable all enabled quota types. However we forget to reset i_data_sem lockdep class. When the inode gets freed and reused, it will inherit this lockdep class (i_data_sem is initialized only when a slab is created) and thus eventually lockdep barfs about possible deadlocks.

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.
