Factor out init_alloc_chunk_ctl() from __btrfs_alloc_chunk(). This function initialises parameters of "struct alloc_chunk_ctl" for allocation. init_alloc_chunk_ctl() handles a common part of the initialisation to load the RAID parameters from btrfs_raid_array. init_alloc_chunk_ctl_policy_regular() decides some parameters for its allocation. The last "else" case in the original code is moved to __btrfs_alloc_chunk() to handle the error case in the common code. Replace the BUG_ON with ASSERT() and error return at the same time.

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.
