If we're doing device replace on a zoned filesystem and discover in
scrub_enumerate_chunks() that we don't have to copy the block group it is
unlocked before it gets skipped.
But as the block group hasn't yet been locked before it leads to a locking
imbalance. To fix this simply remove the unlock.
This was uncovered by fstests' testcase btrfs/163.

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.
