This fixes an infinite loop when repairing "extent past end of inode",
when the extent is an older snapshot than the inode that needs repair.
Without the snaphsots_seen_add_inorder() we keep trying to delete the
same extent, even though it's no longer visible in the inode's snapshot.
Fixes: 63d6e93119 ("bcachefs: bch2_fpunch_snapshot()")

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.
