Subject: [PATCH] crosvm: silence unused code warning for NonZeroU8

After a recent refactoring of display support, this import is only used
when building with the "gpu" feature enabled. Put it behind a cfg check
to avoid a warning when building without gpu support.

BUG=None
TEST=cargo build
TEST=emerge-nami crosvm
