During device shrink pinned/pending chunks (i.e. those which have been deleted/created respectively, in the current transaction and haven't touched disk) need to be accounted when doing device shrink. Presently this happens after the main relocation loop in btrfs_shrink_device, which could lead to making another go in the body of the function. Since there is no hard requirement to perform pinned/pending chunks handling after the relocation loop, move the code before it. This leads to simplifying the code flow around - i.e. no need to use 'goto again'. A notable side effect of this change is that modification of the device's size requires a transaction to be started and committed before the relocation loop starts. This is necessary to ensure that relocation process sees the shrunk device size.

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.
