Coly Li a9c413cd0c bcache: check unsupported feature sets for bcache register 
commit 1dfc0686c29a9bbd3a446a29f9ccde3dec3bc75a upstream.

This patch adds the check for features which is incompatible for
current supported feature sets.

Now if the bcache device created by bcache-tools has features that
current kernel doesn't support, read_super() will fail with error
messoage. E.g. if an unsupported incompatible feature detected,
bcache register will fail with dmesg "bcache: register_bcache() error :
Unsupported incompatible feature found".

Fixes: d721a43ff6 ("bcache: increase super block version for cache device and backing device")
Fixes: ffa4703275 ("bcache: add bucket_size_hi into struct cache_sb_disk for large bucket")
