Current set_btree_ioerr() only accepts @page parameter and grabs extent buffer from page::private. This works fine for sector size == PAGE_SIZE case, but not for subpage case. Add an extra parameter, @eb, for callers to pass extent buffer to this function, so that subpage code can reuse this function. And also add subpage special handling to update btrfs_subpage::error_bitmap.

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.
