When syncing the log, if we fail to allocate the root node for the log
root tree:
1) We are unlocking fs_info->tree_log_mutex, but at this point we have
not yet locked this mutex;
2) We have locked fs_info->tree_root->log_mutex, but we end up not
unlocking it;
So fix this by unlocking fs_info->tree_root->log_mutex instead of
fs_info->tree_log_mutex.
Fixes: e75f9fd194 ("btrfs: zoned: move log tree node allocation out of log_root_tree->log_mutex")

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.
