btree node scan needs to not use the btree node cache: that causes interference from prior failed reads and parallel workers. Instead we need to allocate btree nodes that don't live in the btree cache, so that we can call bch2_btree_node_read_done() directly. This patch tweaks the low level helpers so they don't touch the btree cache lists.

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.
