[PATCH] docs: ext4: fix duplicate Sphinx labels in atomic_writes.rst

[Andre Luiz da Nobrega]

Fixes Sphinx warnings about duplicate reference labels in
Documentation/filesystems/ext4/atomic_writes.rst.

Specifically, the label '.. _atomic_write_bdev_support:' was renamed to
'.. _atomic_write_bdev_support_section:' to ensure label uniqueness
within the document.
