Zilin Guan 5fea61aa1c btrfs: scrub: put bio after errors in scrub_raid56_parity_stripe()
scrub_raid56_parity_stripe() allocates a bio with bio_alloc(), but
fails to release it on some error paths, leading to a potential
memory leak.

Add the missing bio_put() calls to properly drop the bio reference
in those error cases.

Fixes: 1009254bf2 ("btrfs: scrub: use scrub_stripe to implement RAID56 P/Q scrub")

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.
