In bch_cached_dev_run(), free(env[1])|free(env[2])|free(buf) show up three times. This patch introduce out tag in which free(env[1])|free(env[2])|free(buf) are only called one time. If we need to call free() when errors occur, we can set error code to ret, and then goto out tag directly.

README
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.
