btrfs: make set_btree_ioerr accept extent buffer and be subpage compatible

Browse source

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.
