We can error out of an allocation transaction when updating BMBT blocks when things go wrong. This can be a btree corruption, and unexpected ENOSPC, etc. In these cases, we already have deferred ops queued for the first allocation that has been done, and we just want to cancel out the transaction and shut down the filesystem on error. In fact, we do just that for production systems - the assert that we can't have a transaction with defer ops attached unless we are already shut down is bogus and gets in the way of debugging whatever issue is actually causing the transaction to be cancelled. Remove the assert because it is causing spurious test failures to hang test machines.

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.
