For btrfs_folio_assert_not_dirty() and btrfs_folio_set_lock(), we call bitmap_test_range_all_zero() to ensure the involved range has no dirty/lock bit already set. However with my recent enhanced delalloc range error handling, I was hitting the ASSERT() inside btrfs_folio_set_lock(), and it turns out that some error handling path is not properly updating the folio flags. So add some extra dumping for the ASSERTs to dump the involved bitmap to help debug.

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 reStructuredText 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.
