Btrfs: fix stop searching test in replace_one_extent

replace_one_extent searches tree leaves for references to a given extent. It
stops searching if it goes beyond the last possible position.

The last possible position is computed by adding the starting offset of a found
file extent to the full size of the extent. The code uses physical size of the
extent as the full size. This is incorrect when compression is used.

The fix is get the full size from ram_bytes field of file extent item.
