fix some clippy errors that are default deny

Clippy only has 6 lints that are defaulted to deny, which this CL fixes.
The first step to running clippy and establishing our own set of default
deny lints, is to ensure we aren't running afoul of the most common
deny lints.

BUG=None
TEST=cargo clippy --all
