Use BTRFS_MAX_METADATA_BLOCKSIZE and SZ_4K (minimal sectorsize) to calculate this value. And remove one stale comment on the value, in fact with recent subpage support, BTRFS_MAX_METADATA_BLOCKSIZE * PAGE_SIZE is already beyond BTRFS_STRIPE_LEN, just we don't use the full page. Also since we're here, update the BUG_ON() related to SCRUB_MAX_PAGES_PER_BLOCK to ASSERT(). As those ASSERT() are really only for developers to catch early obvious bugs, not to let end users suffer.

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.
