Nathan Chancellor 856dd6c598 ext4: fix unused iterator variable warnings
When CONFIG_QUOTA is disabled, there are warnings around unused iterator
variables:

  fs/ext4/super.c: In function 'ext4_put_super':
  fs/ext4/super.c:1262:13: error: unused variable 'i' [-Werror=unused-variable]
   1262 |         int i, err;
        |             ^
  fs/ext4/super.c: In function '__ext4_fill_super':
  fs/ext4/super.c:5200:22: error: unused variable 'i' [-Werror=unused-variable]
   5200 |         unsigned int i;
        |                      ^
  cc1: all warnings being treated as errors

The kernel has updated to GNU11, allowing the variables to be declared
within the for loop.  Do so to clear up the warnings.

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.
