Matthew Wilcox (Oracle) 0279bed34c Revert "btrfs: fix the file offset calculation inside btrfs_decompress_buf2page()" ...

It seems that af566bdaff was tested against a tree which did not
contain commit 12851bd921 ("fs: Turn page_offset() into a wrapper
around folio_pos()).  Unfortunately it has a bug of its own; on 32-bit
systems, shifting by PAGE_SHIFT will overflow on files larger than 4GiB.
Since page_offset() is now fixed, just revert af566bdaff.

Fixes: af566bdaff (btrfs: fix the file offset calculation inside btrfs_decompress_buf2page())
