It was possible for the ->get_context() operation to fail with a specific error code, which was then not returned to the caller of FS_IOC_SET_ENCRYPTION_POLICY or FS_IOC_GET_ENCRYPTION_POLICY. Make sure to pass through these error codes. Also reorganize the code so that ->get_context() only needs to be called one time when setting an encryption policy, and handle contexts of unrecognized sizes more appropriately.
