btrfs: optimize split page read in btrfs_get_##bits The helper read_extent_buffer is called to do read of the data spanning two extent buffer pages. As the size is known, we can do the read directly in two steps. This removes one function call and compiler can optimize memcpy as the sizes are known at compile time.
