Add a new helper to free zeroed out accounting entries, and use it in bch2_replicas_gc2(); bch2_replicas_gc2() was killing superblock replicas entries if their corresponding accounting counters were nonzero, but that's incorrect - the superblock replicas entry needs to exist if the accounting entry exists, not if it's nonzero, because we check and create the replicas entry when creating the new accounting entry - we don't know when it's becoming nonzero.

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.
