bch2_btree_delete_range_trans() was using btree_trans_too_many_iters() to avoid path overflow, but this was buggy here (and also btree_trans_too_many_iters() is suspect in general). btree_trans_too_many_iters() only returns true when we're close to the maximum number of paths - within 8 - but extent insert/delete assumes that it can use more paths than that. Instead, we need to call bch2_trans_begin() on every loop iteration. Since we don't want to call bch2_trans_begin() (restarting the outer transaction) if the call was a no-op - if we had no work to do - we have to structure things a bit oddly.

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.
