Zheng Qixing aaac92c72d md/raid1: fix memory leak in raid1_run() if no active rdev
[ Upstream commit 5fbcf76e0d ]

When `raid1_set_limits()` fails or when the array has no active
`rdev`, the allocated memory for `conf` is not properly freed.

Add raid1_free() call to properly free the conf in error path.

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.
