Subject: dm ioctl: remove double parentheses

From: Matthias Kaehlcke <mka@chromium.org>

commit e36215d87f301f9567c8c99fd34e6c3521a94ddf upstream.

The extra pair of parantheses is not needed and causes clang to generate
warnings about the DM_DEV_CREATE_CMD comparison in validate_params().

Also remove another double parentheses that doesn't cause a warning.
