Steps to reproduce:

• Test on master commit 278f5de4126883c1fd6bd1e2c08ed8244b563928
• Create a RBD pool
• Create an image in that pool with only `layering` feature on
• Edit the image, Turn on `Exclusive lock`, `Object map`, and `Fast diff` features
• A pop-up shows: [errno 22] error updating features for image b'vol1'
  
• Reload image list and found that features `layering`, `Exclusive lock`, `Object map`, and `Fast diff` are all enabled.
  

• Create an image with `layering` feature and later edit it with `Exclusive lock`, `Object map`: success but `Fast diff` is also on.
• Edit an image with `layering`, `Exclusive lock`, `Object map`, and `Fast diff` feature and uncheck `Fast diff`: success but `Object map` is also off.
• Teuthology test fails on test_image_change_features (tasks.mgr.dashboard.test_rbd.RbdTest)

Seems there are some co-existing behavior for `object map` and `fast diff` features.
