[PATCH 2/5] btrfs: Always limit inline extent size by uncompressed size

[Qu Wenruo <wqu@suse.com>]

Normally when specifying max_inline, we should normally limit it by
uncompressed extent size, as it's the only thing user can control.
(Control the algorithm and compressed data is almost impossible)

Since btrfs is providing *TRANSPARENT* compression, max_inline should
behave the same for both plain and compress data.

So this patch will use @inline_len instead of @data_len in
cow_file_range_inline() so user will know their max_inline mount option
works exactly the same for both plain and compressed data extent.
